* fix: Resolve database encryption atomicity issues and enhance debugging

This commit addresses critical data corruption issues caused by non-atomic
file writes during database encryption, and adds comprehensive diagnostic
logging to help debug encryption-related failures.

**Problem:**
Users reported "Unsupported state or unable to authenticate data" errors
when starting the application after system crashes or Docker container
restarts. The root cause was non-atomic writes of encrypted database files:

1. Encrypted data file written (step 1)
2. Metadata file written (step 2)
→ If process crashes between steps 1 and 2, files become inconsistent
→ New IV/tag in data file, old IV/tag in metadata
→ GCM authentication fails on next startup
→ User data permanently inaccessible

**Solution - Atomic Writes:**

1. Write-to-temp + atomic-rename pattern:
   - Write to temporary files (*.tmp-timestamp-pid)
   - Perform atomic rename operations
   - Clean up temp files on failure

2. Data integrity validation:
   - Add dataSize field to metadata
   - Verify file size before decryption
   - Early detection of corrupted writes

3. Enhanced error diagnostics:
   - Key fingerprints (SHA256 prefix) for verification
   - File modification timestamps
   - Detailed GCM auth failure messages
   - Automatic diagnostic info generation

**Changes:**

database-file-encryption.ts:
- Implement atomic write pattern in encryptDatabaseFromBuffer
- Implement atomic write pattern in encryptDatabaseFile
- Add dataSize field to EncryptedFileMetadata interface
- Validate file size before decryption in decryptDatabaseToBuffer
- Enhanced error messages for GCM auth failures
- Add getDiagnosticInfo() function for comprehensive debugging
- Add debug logging for all encryption/decryption operations

system-crypto.ts:
- Add detailed logging for DATABASE_KEY initialization
- Log key source (env var vs .env file)
- Add key fingerprints to all log messages
- Better error messages when key loading fails

db/index.ts:
- Automatically generate diagnostic info on decryption failure
- Log detailed debugging information to help users troubleshoot

**Debugging Info Added:**

- Key initialization: source, fingerprint, length, path
- Encryption: original size, encrypted size, IV/tag prefixes, temp paths
- Decryption: file timestamps, metadata content, key fingerprint matching
- Auth failures: .env file status, key availability, file consistency
- File diagnostics: existence, readability, size validation, mtime comparison

**Backward Compatibility:**
- dataSize field is optional (metadata.dataSize?: number)
- Old encrypted files without dataSize continue to work
- No migration required

**Testing:**
- Compiled successfully
- No breaking changes to existing APIs
- Graceful handling of legacy v1 encrypted files

Fixes data loss issues reported by users experiencing container restarts
and system crashes during database saves.

- Fix TypeScript compilation by adding esModuleInterop to tsconfig.node.json
- Pass handleLogout from DesktopApp to LeftSidebar for consistent transition behavior

All page transitions now use Tailwind animate-in utilities with 300ms duration for smooth, native-feeling UX

* fix: Add key prop to force animation re-trigger on tab switch

Each page container now has key={currentTab} to ensure React unmounts and remounts the element on every tab switch, properly triggering the slide-in animation

* revert: Remove page transition animations

Page switching animations were not noticeable enough and felt unnecessary.
Keep only the login/logout fullscreen crossfade transitions which provide clear visual feedback for authentication state changes

* feat: Add ripple effect to login/logout transitions

Add three-layer expanding ripple animation during fadeOut phase:
- Ripples expand from screen center using primary theme color
- Each layer has staggered delay (0ms, 150ms, 300ms) for wave effect
- Ripples fade out as they expand to create elegant visual feedback
- Uses pure CSS keyframe animation, no external libraries

Total animation: 800ms ripple + 300ms screen fade

Changes:
- Extend transition duration from 300ms/400ms to 800ms/600ms for more elegant feel

- Slow down ripple animation from 0.8s to 2s with cubic-bezier easing
- Add centered TERMIX logo with monospace font and subtitle
- Logo fades in from 80% scale, holds, then fades out at 110% scale
- Total effect: 1.2s logo animation synced with 2s ripple waves

Creates a premium, branded transition experience

- Hidden on mobile, shows brand identity

Right Side (60% width):
- Centered glassmorphism card with backdrop blur
- Refined tab switcher with pill-style active state
- Enlarged title with gradient text effect
- Added welcome subtitles for better UX
- Card slides in from bottom on load
- All existing functionality preserved

Visual enhancements:
- Tab navigation: segmented control style in muted container
