* fix(cli): safe SQLite db backup/restore (config path + VACUUM INTO)
pad db backup/restore hardcoded ~/.pad/pad.db, so `docker exec pad db
backup` (container sets PAD_DATA_DIR=/data) and Windows layouts broke,
and the SQLite path did a torn io.Copy of pad.db + separate -wal/-shm
copy that could lose or tear in-flight WAL writes.
- Resolve the SQLite path via the server's config loader (PAD_DB_PATH >
PAD_DATA_DIR/pad.db > ~/.pad/pad.db) instead of os.Getenv("HOME").
Covers backup, restore, and migrate-to-pg's --from default.
- Replace the file copy with an online-safe `VACUUM INTO` through the
embedded modernc.org/sqlite driver: one self-contained file, no
-wal/-shm juggling, safe while the server is live.
- Restore refuses when a live server is detected (a running WAL
checkpoint could clobber the restored file); --force overrides.
- docs/backup.md: `pad db backup -o <file>` is the canonical SQLite
path (+ the `docker exec <container> pad db backup -o /data/backup.db`
form); dropped the "PostgreSQL-only" mislabel.
PostgreSQL pg_dump/psql paths are unchanged.
Fixes BUG-1996.

* fix(cli): fail restore on stale sidecar removal + drop unsafe backup doc
Address Codex review P2s:
- Restore: treat a failure to remove a stale -wal/-shm at the target as
fatal (was silently ignored). With single-file VACUUM INTO backups a
leftover sidecar would replay old WAL state over the restored DB.
- docs/backup.md: the SQLite strategy block still recommended a raw
`cp pad.db` daily; point it at `pad db backup --cron` instead.

The 'pad serve' command does not exist in this binary — its canonical
name has been 'pad server start' for some time. Users following the
systemd example in docs/deployment.md would get a non-starting service
today. Six real references fixed:
- cmd/pad/main.go:5714 — migrate-to-pg help text
- cmd/pad/main.go:5795 — 'Next steps' instruction
- docs/backup.md:81,94 — Postgres migration walkthrough
- docs/deployment.md:116 — binary launch example
- docs/deployment.md:164 — systemd ExecStart
Repo-wide grep is now clean of 'pad serve' outside gitignored
v1-archive/ and .pad/ (local workspace data). README.md was already
correct.
