BukeLy 8d9b6a629d fix: use actual embedding_dim instead of environment variable 
CRITICAL FIX: PostgreSQL vector index creation now uses the actual
embedding dimension from PGVectorStorage instead of reading from
EMBEDDING_DIM environment variable (which defaults to 1024).

Root Cause:
- check_tables() called _create_vector_indexes() during db initialization
- It read EMBEDDING_DIM from env, defaulting to 1024
- E2E tests created 1536d legacy tables
- ALTER TABLE failed: "expected 1024 dimensions, not 1536"

Solution:
- Removed vector index creation from check_tables()
- Created new _create_vector_index(table_name, embedding_dim) method
- setup_table() now creates index with correct embedding_dim
- Each PGVectorStorage instance manages its own index

Impact:
- E2E tests will now pass
- Production deployments work without EMBEDDING_DIM env var
- Multi-model support with different dimensions works correctly
