feat: add database schema for integration credentials and config

Phase 2.1: Database schema + credentials storage

Added migration 011 with:
- credentials table: Encrypted OAuth tokens per service
- integration_config table: Base URLs, project names, space keys

Added models:
- Credential: Stores token hash and encrypted token
- IntegrationConfig: Stores service configuration

TDD tests (7 passing):
- Table creation verification
- Column structure validation
- Insert/retrieve operations
- Service uniqueness constraints
- Migration tracking
- Idempotency checks

All tests pass. Schema ready for OAuth2 implementation.

+# Ticket Summary - AI Disclaimer Modal
+
+## Description
+
+Added a mandatory AI disclaimer warning that users must accept before creating new issues. This ensures users understand the risks and limitations of AI-assisted triage and accept responsibility for any actions taken based on AI recommendations.
+
+## Acceptance Criteria
+
+- [x] Disclaimer appears automatically on first visit to New Issue page
+- [x] Modal blocks interaction with page until user accepts or cancels
+- [x] Acceptance is persisted across sessions
+- [x] Clear, professional warning about AI limitations
+- [x] Covers key risks: mistakes, hallucinations, incorrect commands
+- [x] Emphasizes user responsibility and accountability
+- [x] Includes best practices for safe AI usage
+- [x] Cancel button returns user to dashboard
+- [x] Modal re-appears if user tries to create issue without accepting
+
+## Work Implemented
+
+### Frontend Changes
+**File:** `src/pages/NewIssue/index.tsx`
+
+1. **Modal Component:**
+   - Full-screen overlay with backdrop
+   - Centered modal dialog (max-width 2xl)
+   - Scrollable content area for long disclaimer text
+   - Professional styling with proper contrast
+
+2. **Disclaimer Content:**
+   - **Header:** "AI-Assisted Triage Disclaimer"
+   - **Warning Section** (red background):
+     - AI can provide incorrect, incomplete, or outdated information
+     - AI can hallucinate false information
+     - Recommendations may not apply to specific environments
+     - Commands may have unintended consequences (data loss, downtime, security issues)
+   - **Responsibility Section** (yellow background):
+     - User is solely responsible for all actions taken
+     - Must verify AI suggestions against documentation
+     - Must test in non-production first
+     - Must understand commands before executing
+     - Must have backups and rollback plans
+   - **Best Practices:**
+     - Treat AI as starting point, not definitive answer
+     - Consult senior engineers for critical systems
+     - Review AI content for accuracy
+     - Maintain change control processes
+     - Document decisions
+   - **Legal acknowledgment**
+
+3. **State Management:**
+   - `showDisclaimer` state controls modal visibility
+   - `useEffect` hook checks localStorage on page load
+   - Acceptance stored as `tftsr-ai-disclaimer-accepted` in localStorage
+   - Persists across sessions and app restarts
+
+4. **User Flow:**
+   - User visits New Issue → Modal appears
+   - User clicks "I Understand and Accept" → Modal closes, localStorage updated
+   - User clicks "Cancel" → Navigates back to dashboard
+   - User tries to create issue without accepting → Modal re-appears
+   - After acceptance, modal never shows again (unless localStorage cleared)
+
+### Technical Details
+
+**Storage:** `localStorage.getItem("tftsr-ai-disclaimer-accepted")`
+- Key: `tftsr-ai-disclaimer-accepted`
+- Value: `"true"` when accepted
+- Scope: Per-browser, persists across sessions
+
+**Validation Points:**
+1. Page load - Shows modal if not accepted
+2. "Start Triage" button click - Re-checks acceptance before proceeding
+
+**Styling:**
+- Dark overlay: `bg-black/50`
+- Modal: `bg-background` with border and shadow
+- Red warning box: `bg-destructive/10 border-destructive/20`
+- Yellow responsibility box: `bg-yellow-500/10 border-yellow-500/20`
+- Scrollable content: `max-h-[60vh] overflow-y-auto`
+
+## Testing Needed
+
+### Manual Testing
+
+1. **First Visit Flow:**
+   - [ ] Navigate to New Issue page
+   - [ ] Verify modal appears automatically
+   - [ ] Verify page content is blocked/dimmed
+   - [ ] Verify modal is scrollable
+   - [ ] Verify all sections are visible and readable
+
+2. **Acceptance Flow:**
+   - [ ] Click "I Understand and Accept"
+   - [ ] Verify modal closes
+   - [ ] Verify can now create issues
+   - [ ] Refresh page
+   - [ ] Verify modal does NOT re-appear
+
+3. **Cancel Flow:**
+   - [ ] Clear localStorage: `localStorage.removeItem("tftsr-ai-disclaimer-accepted")`
+   - [ ] Go to New Issue page
+   - [ ] Click "Cancel" button
+   - [ ] Verify redirected to dashboard
+   - [ ] Go back to New Issue page
+   - [ ] Verify modal appears again
+
+4. **Rejection Flow:**
+   - [ ] Clear localStorage
+   - [ ] Go to New Issue page
+   - [ ] Close modal without accepting (if possible)
+   - [ ] Fill in issue details
+   - [ ] Click "Start Triage"
+   - [ ] Verify modal re-appears before issue creation
+
+5. **Visual Testing:**
+   - [ ] Test in light theme - verify text contrast
+   - [ ] Test in dark theme - verify text contrast
+   - [ ] Test on mobile viewport - verify modal fits
+   - [ ] Test with very long issue title - verify modal remains on top
+   - [ ] Verify warning colors are distinct (red vs yellow boxes)
+
+6. **Accessibility:**
+   - [ ] Verify modal can be navigated with keyboard
+   - [ ] Verify "Accept" button can be focused and activated with Enter
+   - [ ] Verify "Cancel" button can be focused
+   - [ ] Verify modal traps focus (Tab doesn't leave modal)
+   - [ ] Verify text is readable at different zoom levels
+
+### Browser Testing
+
+Test localStorage persistence across:
+- [ ] Chrome/Edge
+- [ ] Firefox
+- [ ] Safari
+- [ ] Browser restart
+- [ ] Tab close and reopen
+
+### Edge Cases
+
+- [ ] Multiple browser tabs - verify acceptance in one tab reflects in others on reload
+- [ ] Incognito/private browsing - verify modal appears every session
+- [ ] localStorage quota exceeded - verify graceful degradation
+- [ ] Disabled JavaScript - app won't work, but no crashes
+- [ ] Fast double-click on Accept - verify no duplicate localStorage writes
+
+## Security Considerations
+
+**Disclaimer Bypass Risk:**
+Users could theoretically bypass the disclaimer by:
+1. Manually setting localStorage: `localStorage.setItem("tftsr-ai-disclaimer-accepted", "true")`
+2. Using browser dev tools
+
+**Mitigation:** This is acceptable because:
+- The disclaimer is for liability protection, not security
+- Users who bypass it are technical enough to understand the risks
+- The disclaimer is shown prominently and is hard to miss accidentally
+- Acceptance is logged client-side (could be enhanced to log server-side for audit)
+
+**Future Enhancement:**
+- Log acceptance event to backend with timestamp
+- Store acceptance in database tied to user session
+- Require periodic re-acceptance (e.g., every 90 days)
+- Add version tracking to re-show on disclaimer updates
+
+## Legal Notes
+
+This disclaimer should be reviewed by legal counsel to ensure:
+- Adequate liability protection
+- Compliance with jurisdiction-specific requirements
+- Appropriate language for organizational use
+- Clear "Use at your own risk" messaging
+
+**Recommended additions (by legal):**
+- Add version number/date to disclaimer
+- Log acceptance with timestamp for audit trail
+- Consider adding "This is an experimental tool" if applicable
+- Add specific disclaimer for any regulated environments (healthcare, finance, etc.)
