Slice 2 of search-core: the generated SearchVector now applies setweight 'A' to
the subject and 'B' to the body, so ts_rank_cd (added last slice) ranks a subject
match above a body-only mention -- what users expect. Adds an EF migration that
drops/recreates the stored generated column + GIN index (Npgsql emits this
correctly and transactionally).

Verified: the migration DDL was dry-run against the live staging Postgres
(schema + real data) inside a rolled-back transaction -- applies cleanly; and the
weighted ranking (subject 1.0 vs body 0.4 for the same term) was confirmed
directly in Postgres. Build + all 40 tests pass.
