LinYushen 7620a5a7e9 fix(search): LOWER/LIKE for pg_bigm 1.2 index compatibility (#621 )

* fix(search): use LOWER/LIKE instead of ILIKE for pg_bigm 1.2 compatibility

pg_bigm 1.2 on RDS does not support ILIKE index scans. Replace all
ILIKE expressions with LOWER(column) LIKE LOWER(pattern) so the GIN
indexes are utilized. Rebuild gin_bigm_ops indexes on LOWER() expressions.

Closes MUL-482

* fix(search): lowercase pattern in Go, add buildSearchQuery unit tests

- Lowercase phrase/terms in Go (strings.ToLower) so SQL only needs
  LOWER() on the column side, avoiding redundant per-query LOWER() on
  the pattern
- Add 5 unit tests for buildSearchQuery asserting SQL shape: no ILIKE,
  LOWER on columns only, lowercased args, multi-term AND, number match,
  include-closed flag, special char escaping
