Add 8 tests covering the branches that were keeping diff-coverage below
90%: explicit db_path constructor arg, early-return guards when the DB
file is absent, _chmod OSError swallowing in both store classes, and the
supervise volume/env/daemon path in _bundle_launch_spec.
Diff-coverage rises from 89.2% to 94.6% (176/186 changed lines).
Moves _QueueStore → bot_bottle/queue_store.py (public QueueStore) and
_AuditStore → bot_bottle/audit_store.py (public AuditStore). Removes
the public queue_db_path() function; QueueStore resolves the DB path
via host_db_path() on the host, or via the SUPERVISE_DB_PATH env var
in the sidecar container (internal mechanism, not public API).
Adds queue_store.py and audit_store.py to Dockerfile.sidecars so the
sidecar bundle picks them up. Updates __all__ in supervise.py.

Sixth per-module ratchet under ADR 0004. Cover the queue/audit
malformed-input and fallback branches:
- path helpers (bot_bottle_root, queue_dir_for_slug,
_id_from_proposal_filename non-match)
- read_proposal / read_response reject non-object JSON
- list_pending_proposals skips unreadable/non-dict/incomplete
proposals and ones with a response already present
- wait_for_response tolerates a malformed or incomplete response file
and then times out at the deadline
- read_audit_entries returns [] for a missing log and skips blank /
non-JSON / non-dict / missing-field lines
- the fcntl flock helpers swallow OSError on a bad fd
supervise.py: 89% -> 99%. The one remaining line is an unreachable
`continue` (glob already guarantees the .proposal.json suffix).
