login_user now records the user's current password_changed_at on the
session. The next commit will use this marker to invalidate sessions
whose password has been rotated under them.

Single source of truth for the password policy, to be reused by the
upcoming /profile/password endpoint and (optionally) the create-user
CLI.

- validate instance names at the host lib and web boundary against
[a-z0-9][a-z0-9_-]{0,63} to prevent path traversal via Server.name
- fail-closed on SECRET_KEY: load_config returns None when env unset,
create_app raises if missing or "dev" outside TESTING
- close login timing oracle by hashing a dummy digest when the user
is not found, equalizing response time
- set SESSION_COOKIE_SECURE outside TESTING
- delete_instance tolerates stop_service and fusermount3 failures so
partially-initialized instances clean up without contract breaks;
drops the is_mount() preflight that violated AGENTS.md
- document claim_next_job's single-process assumption
- clarify emit_step contract via docstring
