feat: settings page exercises the password-change endpoint

The 0.10.0 backend endpoint had no UI caller — the audit flagged it
as either-ship-a-form-or-remove-the-endpoint dead code. Shipping the
form, plus the bearer-token-keeps-working regression test the audit
asked for to pin the docstring contract.

Backend:
- New test change_password_via_bearer_leaves_bearer_working asserts
  that PATCH /me/password called with Authorization: Bearer wipes
  cookie sessions but leaves the bearer (api_token) intact and usable
  — matches the docstring claim that bot tokens are opt-in to revoke.

Frontend:
- lib/api/auth.ts: new changePassword(input) wrapping PATCH
  /v1/auth/me/password. Vitest covers happy 204, 401 unauthenticated
  (wrong current), 400 invalid_input (weak new) — same envelope
  parsing shape used elsewhere.
- routes/settings/+page.svelte: minimal form with current /
  new / confirm fields, derived passwordsMatch + canSubmit guards
  (submit stays disabled until current is filled, new is ≥8 chars,
  new == confirm). Shows the API's message inline on failure.
  Documents the "other devices signed out, bot tokens stay" UX in a
  short hint.
- routes/+layout.svelte: new "Settings" link in the session-aware
  nav (between username and Logout) for authed users only.
- e2e/settings.spec.ts (5 cases): nav link reaches the form,
  successful change shows confirmation + clears the form, 401
  surfaces inline, password mismatch keeps submit disabled, anonymous
  user gets a sign-in prompt instead of the form.

Lockstep version bump to 0.11.0.
