fix: add table qualification to filters_idx WHERE clause to resolve ambiguous column errors in reverse join

[halconel]

Problem

When using join_keys with filters_idx, SQL queries with JOIN failed with:

psycopg2.errors.AmbiguousColumn: column reference "id" is ambiguous

The sql_apply_filters_idx_to_subquery function used sa.column(i) without table qualification, which worked for simple SELECT queries but failed for JOIN queries with multiple tables sharing column names.

Solution

Added optional tbl parameter to sql_apply_filters_idx_to_subquery:

• When tbl is provided → use tbl.c[i] (qualified column name)
• When tbl=None → use sa.column(i) (backward compatibility)

Updated all call sites to pass table reference.

What this fixes

✅ Reverse join now works correctly with join_keys and filters_idx
✅ Solves LEFT JOIN issues with asynchronously updated tables
✅ Maintains backward compatibility
