Subject: [PATCH] Add admin password change flow (closes #65) (#83)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an authenticated, CSRF-protected flow that lets a user change their own password from the profile page.

## Route

- New `POST /password` under the `/user/{username}` group in `setupUserRoutes` (`internal/server/routes.go`). That group already applies `CSRF`, `NoCache`, and `RequireAuth`, so the new endpoint inherits all three.

## Handler (`internal/handlers/profile.go`)

- `HandlePasswordChange` enforces own-user access: the `{username}` path parameter must equal the session username (same 403 rule `HandleProfile` uses). This check plus the session lookup is factored into a shared `profileOwnerOrDeny` helper now used by both handlers.
- Parses `current_password`, `new_password`, and `confirm_password` (body size limited via `http.MaxBytesReader`).
- Verifies the current password with `database.VerifyPassword` against the stored hash.
- Requires the new password to be non-empty and equal to the confirmation.
- Hashes the new password with `database.HashPassword` — the same Argon2id helper used to bootstrap the admin user — and persists it on the user row. No new crypto.
- Re-renders the profile page with a clear success or error message. Wrong current password, empty new password, and mismatched confirmation are each rejected with their own message and leave the stored hash unchanged.

## Template (`templates/profile.html`)

- Adds a "Change Password" card with current / new / confirm password fields plus the hidden `csrf_token` (matching the login form's CSRF embedding).
- Renders success/error alerts using the existing `alert-success` / `alert-error` styles. No new CSS classes, so no Tailwind rebuild is required.

## Tests (`internal/handlers/profile_test.go`)

- `TestHandlePasswordChange_Success`: seeds a user, posts a valid change, asserts success message and that the stored hash changed and verifies against the new password.
- `TestHandlePasswordChange_WrongCurrentPassword`: posts a wrong current password, asserts the rejection message and that the stored hash is unchanged.

Validated with `docker build .` (fmt-check, lint, test, build) — exit 0.

Closes #65
