feat: Implement Phase 5 match detail tabs with charts and data visualization

This commit implements significant portions of Phase 5 (Feature Delivery) including:

Chart Components (src/lib/components/charts/):
- LineChart.svelte: Line charts with Chart.js integration
- BarChart.svelte: Vertical/horizontal bar charts with stacking
- PieChart.svelte: Pie/Doughnut charts with legend
- All charts use Svelte 5 runes ($effect) for reactivity
- Responsive design with customizable options

Data Display Components (src/lib/components/data-display/):
- DataTable.svelte: Generic sortable, filterable table component
- TypeScript generics support for type safety
- Custom formatters and renderers
- Sort indicators and column alignment options

Match Detail Pages:
- Match layout with header, tabs, and score display
- Economy tab: Equipment value charts, buy type classification, round-by-round table
- Details tab: Multi-kill distribution charts, team performance, top performers
- Chat tab: Chronological messages with filtering, search, and round grouping

Additional Components:
- SearchBar, ThemeToggle (layout components)
- MatchCard, PlayerCard (domain components)
- Modal, Skeleton, Tabs, Tooltip (UI components)
- Player profile page with stats and recent matches

Dependencies:
- Installed chart.js for data visualization
- Created Svelte 5 compatible chart wrappers

Phase 4 marked as complete, Phase 5 at 50% completion.
Flashes and Damage tabs deferred for future implementation.

Note: Minor linting warnings to be addressed in follow-up commit.
