feat(profile): self-service name/email/password + desktop installers in CI

Self-service profile: any signed-in user edits their OWN fullName/email and
changes their OWN password (proving the current one), without any user:*
permission. New routes PUT /api/auth/profile + /api/auth/password act only on
req.user.sub (cannot touch username/role), CSRF-guarded; SPA screen at /profile
reachable from the header username chip. email added to the session view +
SessionUser. 7 tests (routes/profile.test.ts); 148 server tests green.

Desktop in CI: new .gitea/workflows/build-desktop.yml builds .deb + .AppImage
on every push to dev/main and uploads them as unsigned workflow artifacts
(per-commit test build). Signed/versioned release stays on release.yml (tag v*).

Wiki: local-jwt-auth (self-service routes), desktop-shell-tauri (two-workflow CI
split), log entry.
