- api.ts: switch baseURL from http://localhost:8001/api/v1 to relative
/api/v1. Both nginx (prod) and vite (dev) already proxy /api/ to the
backend, so requests become same-origin and the app works from any
host (LAN IP, reverse proxy, another machine) with no CORS dance.
- backend CORS: open to "*" as a fallback for the rare direct-hit case;
the normal flow is same-origin via the proxy and never touches CORS.
- App layout: move FilterBar and DiscardActionBar inside the main
content column (right of the left sidebar) so the filter row no
longer bleeds across the sidebar.
- FilterBar: justify-center the pills so they sit centered above the
timeline. Clear-all uses ml-2 instead of ml-auto.
- KeyboardHints: convert to a floating, glassy pill pinned bottom-
center (fixed positioning + backdrop-blur + ring) instead of a flat
toolbar row. Removed from the column layout — now mounted as an
overlay sibling.
