Introduced ConnectionManager to support offline-first architecture:
- New internal/db/connection.go with thread-safe connection management
- Lazy connection establishment (5s timeout, 10s cooldown)
- Automatic ping caching (30s interval) to avoid excessive checks
- Updated middleware/offline.go to use ConnectionManager.IsOnline()
- Updated sync/worker.go to use ConnectionManager instead of direct DB
This enables the application to start without MariaDB and gracefully
handle offline/online transitions.
Part of Phase 2.5: Full Offline Mode
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Fixed two critical issues preventing offline-first operation:
1. **Instant startup** - Removed blocking GetDB() call during server
initialization. Server now starts in <10ms instead of 1+ minute.
- Changed setupRouter() to use lazy DB connection via ConnectionManager
- mariaDB connection is now nil on startup, established only when needed
- Fixes timeout issues when MariaDB is unreachable
2. **Offline mode nil pointer panics** - Added graceful degradation
when database is offline:
- ComponentService.GetCategories() returns DefaultCategories if repo is nil
- ComponentService.List/GetByLotName checks for nil repo
- PricelistService methods return empty/error responses in offline mode
- All methods properly handle nil repositories
**Before**: Server startup took 1min+ and crashed with nil pointer panic
when trying to load /configurator page offline.
**After**: Server starts instantly and serves pages in offline mode using
DefaultCategories and SQLite data.

- Added CountErroredChanges() method to count only pending changes with LastError
- Previously, error count included all pending changes, not just failed ones
- Added /api/sync/info endpoint with proper error count and error list
- Added sync info modal to display sync status, error count, and error details
- Made sync status indicators clickable to open the modal
- Fixed disconnect between "Error count: 4" and "No errors" in the list

Root cause: admin_pricing.html declared 'const showToast' while base.html
already defined 'function showToast', causing SyntaxError that prevented
all JavaScript from executing on the admin pricing page.
Changes:
- Removed duplicate showToast declaration from admin_pricing.html (lines 206-210)
- Removed debug logging added in previous commit
- Kept immediate function calls in base.html to ensure early initialization
This fixes the issue where username and "Администратор цен" link
disappeared when navigating to /admin/pricing.

- Added immediate calls to checkDbStatus() and checkWritePermission() in base.html
- Calls happen right after function definitions, before DOMContentLoaded
- Added console.log statements to track function execution and API responses
- Removed duplicate calls from admin_pricing.html to avoid conflicts
- This will help diagnose why username and admin link disappear on admin pricing page

- Parse URLSearchParams to detect ?tab=pricelists on page load
- Load tab from URL or default to 'alerts'
- Fixes redirect from /pricelists to /admin/pricing?tab=pricelists
This resolves the critical UX issue where users redirected from
/pricelists would see the 'alerts' tab instead of 'pricelists'.

- Pass originalHTML through syncAction function chain
- Simplify finally block by restoring original button innerHTML
- Remove hardcoded button HTML values (5 lines reduction)
- Improve maintainability: button text changes won't break code
- Preserve any custom classes, attributes, or nested elements
This fixes the issue where originalHTML was declared but never used.
