feat: Implement Phase 1 critical features and fix API integration

This commit completes the first phase of feature parity implementation and
resolves all API integration issues to match the backend API format.

## API Integration Fixes

- Remove all hardcoded default values from transformers (tick_rate, kast, player_count, steam_updated)
- Update TypeScript types to make fields optional where backend doesn't guarantee them
- Update Zod schemas to validate optional fields correctly
- Fix mock data to match real API response format (plain arrays, not wrapped objects)
- Update UI components to handle undefined values with proper fallbacks
- Add comprehensive API documentation for Match and Player endpoints

## Phase 1 Features Implemented (3/6)

### 1. Player Tracking System ✅
- Created TrackPlayerModal.svelte with auth code input
- Integrated track/untrack player API endpoints
- Added UI for providing optional share code
- Displays tracked status on player profiles
- Full validation and error handling

### 2. Share Code Parsing ✅
- Created ShareCodeInput.svelte component
- Added to matches page for easy match submission
- Real-time validation of share code format
- Parse status feedback with loading states
- Auto-redirect to match page on success

### 3. VAC/Game Ban Status ✅
- Added VAC and game ban count/date fields to Player type
- Display status badges on player profile pages
- Show ban count and date when available
- Visual indicators using DaisyUI badge components

## Component Improvements

- Modal.svelte: Added Svelte 5 Snippet types, actions slot support
- ThemeToggle.svelte: Removed deprecated svelte:component usage
- Tooltip.svelte: Fixed type safety with Snippet type
- All new components follow Svelte 5 runes pattern ($state, $derived, $bindable)

## Type Safety & Linting

- Fixed all ESLint errors (any types → proper types)
- Fixed form label accessibility issues
- Replaced error: any with error: unknown + proper type guards
- Added Snippet type imports where needed
- Updated all catch blocks to use instanceof Error checks

## Static Assets

- Migrated all files from public/ to static/ directory per SvelteKit best practices
- Moved 200+ map icons, screenshots, and other assets
- Updated all import paths to use /images/ (served from static/)

## Documentation

- Created IMPLEMENTATION_STATUS.md tracking all 15 missing features
- Updated API.md with optional field annotations
- Created MATCHES_API.md with comprehensive endpoint documentation
- Added inline comments marking optional vs required fields

## Testing

- Updated mock fixtures to remove default values
- Fixed mock handlers to return plain arrays like real API
- Ensured all components handle undefined gracefully

## Remaining Phase 1 Tasks

- [ ] Add VAC status column to match scoreboard
- [ ] Create weapons statistics tab for matches
- [ ] Implement recently visited players on home page
