Closes #1727 and #2257 — the same bug in two services written months apart.

AppLog.created_at is `timestamp with time zone`. asyncpg binds a Python str as
VARCHAR and Postgres has no `timestamptz >= text` operator, so both of these
raised when Postgres planned the query:

  notifications.check_due_tasks   AppLog.created_at >= today.isoformat()
  logging.get_logs                AppLog.created_at >= <raw request.args str>

#1727 was the worse of the two because a per-user `except Exception` swallowed
it: reminder emails silently never sent, and the only outward trace was an
hourly traceback in the Postgres log. It has been open since 2026-07-19 with the
diagnosis written and the fix never applied. #2257 has no swallowing handler, so
it merely breaks the admin log viewer's date filters outright.

notifications: `utc_day_start(day)` returns midnight UTC as an AWARE datetime.
Deliberately not the bare `date` the original diagnosis suggested — comparing
timestamptz to date does work via an implicit cast, but Postgres resolves that
cast in the SESSION's TimeZone, so the dedup window would drift with a server
setting nobody remembers is load-bearing.

logging: `parse_filter_datetime()` converts the query-string value to an aware
UTC datetime; unparseable input returns None so the filter is skipped rather
than 500ing the viewer. It also fixes a bug the naive fix would have introduced
— `date_to=2026-07-30` parses to midnight, so `<=` would exclude the entire day
the user asked for. Date-only upper bounds now run to 23:59:59.999999, while a
value carrying an explicit time is left as given.

The guard is the point. This class is invisible to ordinary testing: the failure
happens when Postgres plans the query, not when Python builds it, so no unit
test that doesn't execute SQL can see it. tests/test_timestamp_filters.py fails
CI on two shapes —

  1. a local bound to .isoformat() compared against a *_at column   (#1727)
  2. a str-ANNOTATED PARAMETER compared against a *_at column       (#2257)

Shape 2 is the one that matters. Nothing in logging.py looks date-ish, so a
guard built only from #1727's shape finds nothing there — which is exactly how
the second instance survived. Verified by replaying both checks against the
pre-fix files out of git: shape 1 catches `today_str`, shape 2 catches
`date_from`/`date_to`, and the current tree is clean.

Found by grepping for siblings after fixing #1727 — the third instance today of
"the second place nobody checked", after #2245.

bvandeusenandClaude Opus 4.8 b255a0f90e refactor: rename package fabledassistant -> scribe (code-only)
CI & Build / Python lint (push) Successful in 3s

CI & Build / Python tests (push) Successful in 54s

Renames src/fabledassistant -> src/scribe and all imports, plus the
default DB name and DB user/password (fabled -> scribe) in config +
compose. 952 refs / 154 files. Reverses the old 'internal name stays
fabledassistant' convention.

Code-only: live databases are still physically named 'fabledassistant'.
Deployed environments must set POSTGRES_DB / POSTGRES_USER (or rename the
DB) since the defaults now resolve to 'scribe'. Repo (FabledScribe), git
host (fabledsword), MCP (fabled-git) and the image name (fabledscribe)
are intentionally unchanged.

ruff check src/ clean locally; CI (typecheck + pytest) is the gate.
