anti 87cb61c8b2 feat(realism): synthetic-files browser API
Adds GET /api/v1/realism/synthetic-files (paginated list, filters by
decky_uuid, persona, content_class) and
GET /api/v1/realism/synthetic-files/{uuid} (single row with last_body
and a truncated:bool flag set when the stored body is at the 64KB cap).

Repo gains count_synthetic_files() and get_synthetic_file(uuid). The
list view drops last_body to keep the wire payload bounded; the detail
endpoint is the only path that returns it. Read-only — orchestrator
remains the sole writer.

"""GET ``/api/v1/realism/synthetic-files`` — browse planted realism files.
The orchestrator's realism worker grows synthetic files on each decky
(notes, TODOs, drafts, scripts, log lines, canary artifacts). The
:class:`~decnet.web.db.models.realism.SyntheticFile` table is the
canonical record of what's been planted where; this endpoint lets
operators inspect the lineage without ssh'ing into a decky.
Read-only. No writes — the orchestrator is the sole writer; the
dashboard is observation surface only.
The body preview (``last_body``) is repo-clipped at 64 KB
(:data:`SYNTHETIC_FILE_BODY_LIMIT`); when the original was larger the
detail response carries ``truncated: true`` so the operator knows what
they're looking at.
