PR-3 of the Fristen+Termine unification. Both routes now serve the shared
shell built by renderEvents() — the per-type pages (deadlines.tsx /
appointments.tsx and their client bundles) are deleted entirely.
Hydration is baked at build time, not at request time: build.ts emits
events-deadlines.html and events-appointments.html, each carrying an
inline `window.__PALIAD_EVENTS__={"defaultType":"…"}` script in <head>.
The Go handlers ServeFile the matching artefact, no placeholder swap
needed (cleaner than the dashboard pattern for a single static flag).
Sidebar entries unchanged — "Fristen" still points at /deadlines,
"Termine" at /appointments. Both highlight correctly because each
artefact passes the matching currentPath into <Sidebar />.
Detail / new / calendar pages stay type-specific (out of scope per
task brief). Old endpoints /api/deadlines + /api/appointments remain
live for the calendars, project-detail panes, and CalDAV consumers.
Net: -981 lines (drops the duplicated chrome of the two old pages
in favour of one shared shell).
go build/vet/test ./... clean. bun run build clean.
