[17.0][FIX] base_geoengine: filtered domain geo operators

[zamberjo]

Odoo evaluates ir.rule domains in-memory via BaseModel._filter_access_rules_python() → filtered_domain(), which has a hardcoded operator dispatch (if/elif chain) that raises ValueError for any operator it doesn't recognize.

While base_geoengine already patches expression.TERM_OPERATORS and __leaf_to_sql to support geo operators (geo_within, geo_intersect, etc.) during SQL query compilation, the Python-side filtered_domain() is a completely separate code path that was never extended.

This fix patches filtered_domain to detect geo operator leaves and fall back to a SQL search() call (where PostGIS can resolve them), following the same delegation pattern Odoo already uses for child_of and parent_of operators.

Non-geo domains are unaffected and continue using the original in-memory evaluation.
