trace_db_call no longer takes an OpenTelemetry Context: it opens a
db.<query_type>.<operation> span (same name via otel.name, same
db.query_type / db.operation attrs) on the caller's ambient tracing span
and runs the DAO body inside it. The cx / ctx / context parameter is gone
from every DAO trait method, impl and call site, and from the helpers and
background drains that only threaded it.
The remaining request-handler spans (files, tags, faces, image, video,
favorites, duplicates, memories) move to #[instrument]; the
Context::current_with_span / with_remote_span_context plumbing is gone, as
is extract_context_from_request (the tracing-actix-web root span covers
it). otel::set_span_attributes replaces BoxedSpan::set_attributes.
Background-job raw spans (thumbnails, video actors) are left for #142.
tests/otel_db_spans.rs pins name, attributes, status and nesting (across
an instrumented spawn); otel_traceparent now uses an #[instrument]
handler. CLAUDE.md documents the tracing conventions.

Closes#127.
Grows user_ai_prefs with five nullable owner-default columns and makes
them the server-side fallback layer: request param -> stored pref ->
hard default, at insight generation (agentic + standard), all three
insight-chat turn variants, and reel creation.
- PUT /prefs accepts the fields with the existing three-state partial
update semantics (TriState generalized to TriState<T> for the numeric
reel_max_segments); validation (canonical BackendKind::parse,
MemoriesSpan::from_str) runs before any write.
- GET /prefs returns the new fields.
- capture_prefs reads the existing row and carries the AI owner-defaults
through unchanged (the upsert overwrites all columns), mirroring only
the effective reel span/segments.
- MemoriesSpan gains Display + FromStr so stored spans round-trip
losslessly.
1463/0 tests (+27), clippy clean.
- GET /prefs (JWT): current row or empty {voice, library, display_tz,
updated_at} shape — snake_case, 200 with nulls when no row
- PUT /prefs (JWT): three-state partial update (omitted=unchanged,
explicit null=clear, value=set) via hand-rolled TriState deserializer —
serde derive conflates omitted with explicit null on Option<Option<T>>
- display_tz validated against chrono-tz before any write; invalid → 400,
nothing written. tz_offset_minutes (frozen legacy) preserved verbatim
- GET /timezones (public): chrono_tz::TZ_VARIANTS — exactly the domain
Tz::from_str accepts, so picker list and validation can't drift
- No migration; existing columns only. capture_prefs (POST /reels) untouched
- 14 tests: 3 GET /prefs, 7 PUT /prefs (incl. auth-gate), 2 /timezones,
2 pure merge_patch. Full suite 1436 passed / 0 failed
