Add filter support to semantic search

[jazairi]

Why these changes are being introduced:

Semantic searches ignore filters, meaning that
when semantic mode is enabled in the UI, the tabs
do not filter as intended.

Relevant ticket(s):

• USE-593

How this addresses that need:

SemanticQueryBuilder now applies FilterBuilder
filters to semantic queries, making it consistent
with lexical and hybrid search.

Side effects of this change:

We should consider adding regression test coverage in the TIMDEX UI repo.

Pull request overview

This PR updates semantic search query construction so UI tab/aggregation filters are applied in semantic mode, aligning behavior with lexical and hybrid search modes.

Changes:

• Apply FilterBuilder-generated filters to the semantic query returned from the semantic-builder Lambda.
• Update existing semantic query builder test expectations to include an explicit filter clause.
• Add new tests covering source_filter, content_type_filter, and the “no filters” case for semantic queries.
