Phase 1: identity, sessions, audit, frontend shell

AD sign-in over LDAPS (search with the service account, bind as the user,
nested groups through LDAP_MATCHING_RULE_IN_CHAIN, disabled accounts refused),
roles as the union of PS-* groups mapped by a table derived from the seeded
departments. Server-side sessions with idle, lock and absolute timeouts, Origin
and X-Requested-With check, step-up unlock. Optional Argon2id PIN set with the
domain password; PIN sign-in by employee ID on registered devices only; five
wrong attempts disable the PIN, three wrong at unlock or signature end the
session. Rate limits per account and per address before any bind. Devices,
signatures table and sign helper, audit rows for every identity event, SSE over
LISTEN/NOTIFY with presence. Account settings and Admin APIs and screens
(AD view, devices, PIN clearing, group map with missing-group flags, refresh
from AD now). CLI ad-groups --list and ad-refresh. Migration 0002.

Frontend: real sign-in (password tab, PIN keypad on registered devices), lock
screen, role switcher, Account settings, Admin shell, screen placeholders.

CI: Samba AD DC container (PSTEST.LOCAL) with a generated CA, 49 of the 50
groups plus one extra, 17 test users; wired into the CI compose overlay and
the Gitea workflow; Playwright sign-in scenario.

Verified on docker-1: 171 server tests green inside the CI stack against
PostgreSQL and the Samba DC, 48 frontend tests, 8 Playwright scenarios against
the live stack (password and PIN sign-in, lock and unlock, Admin group map).
Findings recorded in the docs: the DC needs CAP_SYS_ADMIN, a hidden tab locks
only after a minute as the old build did,
and the app uses the alias ps-app for Playwright because "app" is on
Chromium's HSTS preload list.

 ### Added
 
+- Phase 1: identity. Sign-in with the domain account and password against PESCO's Active Directory over LDAPS (search with the service account, then bind as the user; nested groups resolved; disabled accounts refused). Roles are the union of a person's `PS-*` groups, mapped by a table derived from the department list.
+- Server-side sessions: HttpOnly, SameSite=Strict cookie, idle sign-out after 15 minutes, absolute 12 hours for password sessions and 10 hours for PIN sessions, server-recorded lock after 3 idle minutes or a tab hidden for over a minute, step-up unlock with PIN or password. Origin and `X-Requested-With` check on every state-changing request.
+- Optional Packet Station PIN, 6 to 12 digits, set by the user with their domain password, hashed with Argon2id. PIN sign-in by employee ID on registered devices only. Five wrong attempts disable the PIN; three wrong attempts at unlock or signature end the session.
+- Rate limits before any AD bind: 5 failed attempts per account per 5 minutes then a 10-minute cooldown, 30 per client address per 5 minutes.
+- Device registration by an Admin or a shop Supervisor in a password session, with a device cookie; devices listed and revocable by Admin.
+- Signatures table and the `sign` helper for the sign-off actions of later phases.
+- Audit rows for every identity event through the hash-chained audit log.
+- `GET /api/events`: server-sent events over PostgreSQL LISTEN/NOTIFY with presence.
+- Account settings: AD details, PIN create or change, sessions and sign-out-others, own access log, register this device.
+- Admin: read-only AD view of users and any account, devices, PIN clearing with a reason, the group map with missing-group flags, sign-in attempts, and "Refresh from AD now", which enumerates the groups' members and creates or refreshes the users.
+- Frontend: real sign-in (password tab, PIN keypad tab on registered devices), lock screen, role switcher, Account settings, Admin shell, placeholders for the screens of later phases.
+- CLI: `packetstation ad-groups --list` and `packetstation ad-refresh`.
+- Migration 0002: users keyed on the AD objectGUID, user_roles, sessions, devices, user_pins, signin_attempts, signatures, departments and stations seeded with the 18 departments.
+- CI: a Samba Active Directory domain controller container (`PSTEST.LOCAL`) with a generated CA, seeded groups and test users; the CI compose overlay and Gitea workflow run it; a Playwright sign-in scenario runs against the stack.
