feat(maintenance): reminders CLI + systemd timer drop-in

Phase 3-4 of maintenance reminders.

scripts/maintenance-reminders.ts: thin CLI that opens the same
pg pool as the app and calls runRemindersOnce. Flags:
--soon-days N (default 7), --company <id> (default all),
--dry-run (count without firing), --backfill (mark all currently
due as already-sent, mutually exclusive with --dry-run). Prints a
single-line JSON summary so journald/jq handles it cleanly.

package.json: + reminders:check script.

DEPLOYMENT.md: documents the systemd .service + .timer pair for
06:00 daily, with Persistent=true so a missed run during host
downtime still fires on next boot. Includes the first-deploy
protocol (--dry-run to scope, then either let day-one alert or
--backfill for a clean slate).

+### Maintenance reminders timer
+
+The app records `next_due_at` on every time-based maintenance schedule but does not poll itself. A daily systemd timer runs `pnpm run reminders:check`, which scans for schedules entering the 7-day warning window or already overdue and fans out via the existing in-app + email + Matrix notifier. Re-runs are idempotent — `maintenance_reminders_sent` deduplicates per `(schedule, kind, due_at)`.

+
+**First-run protocol** to avoid a deluge of stale alerts on day one:
+
+```bash
+# Inspect what would fire without notifying.
+sudo -iu ops bash -lc 'cd ~/buildfor_life_ops && pnpm run reminders:check -- --dry-run'
+
+# If the count is reasonable, run normally — the timer will pick up subsequent
+# windows automatically. Or, if you want a clean slate, mark everything
+# currently-due as already-notified (no fan-out), so day-one alerts only
+# new breaches:
+sudo -iu ops bash -lc 'cd ~/buildfor_life_ops && pnpm run reminders:check -- --backfill'
+```
+
+Logs end up in `journalctl -u buildfor_life_ops-reminders.service`. Each run prints a single JSON line (`{ ok, scanned, fired, skippedDedup, noRecipients, ... }`) so `journalctl --output=cat | grep '"ok":true' | jq` gives a clean trend view.

+
+### 5b — pending Phase 5 items
+
+- **Reports** — cross-cutting outputs (monthly building roll-up, annual asset summary). Per-domain CSV exports already exist; this is the aggregated/scheduled layer
+- **Cross-app APIs** — wire `buildfor_life_ops` to siblings `buildfor_life_budget` and `buildfor_life_repair` so decisions can link to budget line items and repair tickets
+
+### 6 — quality-of-life backlog
+
+Things that came up after the original roadmap was written. Not prioritised — pull whichever the next stakeholder ask depends on.
+
+- **Maintenance reminders** — cron-style trigger that fires `maintenance_event_recorded` / `task_assigned` notifications when `next_due_at` crosses a threshold. The notification fan-out (app + email + Matrix) is already there; only the scheduler is missing
+- **OIDC SSO** — env vars + schema are wired (`OIDC_ENABLED`, `OIDC_ISSUER`, etc.), but the route handlers were never written
+- **Self-service password reset** — currently admin-initiated only via `pnpm run create-user`
+- **Permission inheritance for sub-properties** — RBAC is per-company today; "manager of Building A" does not imply "manager of Apt 3B"
+- **Bulk property CSV import** — "create N apartments under this building" in one upload, mirroring the existing expenses CSV importer
+- **"Move to parent" quick action** — UI sugar over the existing edit form for re-parenting
+- **Audit log viewer** — `audit_action` enum + audit infrastructure exists, but no UI to browse it
+- **Project ↔ property linking** — they're disjoint today; many real workflows want "this project is happening at this property"
