- Replace sidebar org dropdown with a header link/menu (left of theme toggle) that
includes a "New Organization" entry opening the create dialog
- Self-host Inter via @fontsource-variable/inter instead of relying on system fonts
- Wire up real feature<->tag assignment (was UI-only before): expose Tags on
FeatureResponse, add assign/remove endpoints, make tag chips in the feature
detail dialog toggle assignment, and show up to 5 tags (+ellipsis) in the
features table next to the segment-override icon
- Normalize all API routes to singular/plural REST convention: singular resource
name when addressing one item by id/key (e.g. /feature/{id}), plural for
list/create endpoints (e.g. /features). Updated every controller, the admin
frontend API clients, and affected tests to match
Instruments FeatureEvaluationService with System.Diagnostics.Metrics (Counter + IMeterFactory). Accumulates per-feature/day evaluation counts in-process, flushed every 30s to a new FeatureUsageDaily Postgres table via PostgreSQL ON CONFLICT upsert. Caches dashboard query results for 180s in IMemoryCache. New GET /api/v1/environments/{id}/usage endpoint returns top-10 features last day and 14-day per-day breakdown. Admin dashboard shows two ApexCharts bar charts: top features and evaluations by day with per-flag hover tooltip.
