Add initial Mini Vibeathon competition domain

[julianromli]

Summary

• add the initial competition schema, seed data, and shared competition types
• implement the first public competition routes, feed/detail components, and submit flow scaffolding
• extend the unified comments system and admin comment mapping for competition entries
• add a basic admin competitions board entry point and sitemap updates

Verification

• npx @biomejs/biome check on the changed competition/comment files
• attempted npx --package typescript tsc --noEmit but the cloud image does not have the workspace dependencies installed, so the run is blocked by repo-wide missing-module errors before it can validate this slice

Preserve numeric project IDs in report title lookup

Project reports can now render as Unknown Project because this map stores raw projects.id values (typically numbers from Supabase for integer columns) but later lookups use entityInfo.entityId as a string. In JavaScript Map, numeric key 1 and string key '1' are different, so project titles are missed whenever a reported comment belongs to a project.

Constrain active competition selection to the live date window

This query picks the most recent row with status = 'active' but does not enforce starts_at <= now < ends_at. If multiple competitions are marked active (or one is left active after ending), pages that rely on getActiveCompetition() can bind to the wrong competition, causing submission/vote flows to point at a closed or not-yet-open event.
