- Convert all sqlx::query!() and sqlx::query_scalar!() compile-time
macros to runtime sqlx::query() and sqlx::query_scalar() with .bind()
- Affected files: segment_tracker.rs, processor.rs, callbacks.rs
- This removes the dependency on .sqlx/ directory for offline mode
- Update Dockerfile to remove SQLX_OFFLINE=true and .sqlx COPY
- Stream server can now compile without a live database connection
The compile-time macros required either a DATABASE_URL at build time or
a .sqlx directory with cached query metadata (neither was available).
Runtime queries trade compile-time SQL validation for buildability.
Addresses audit finding: debt item 1 (stream server compilation).
