feat(doctrine): deprecate the legacy SearchFilter/Boolean/Numeric/BackedEnum/OrderFilter

These multi-strategy and type-specific filters are superseded by the
canonical QueryParameter-based set and are removed in 6.0:

- SearchFilter  -> ExactFilter / PartialSearchFilter / StartSearchFilter / EndSearchFilter (per strategy)
- BooleanFilter -> ExactFilter + boolean nativeType
- NumericFilter -> ExactFilter + numeric nativeType
- BackedEnumFilter -> ExactFilter + backed-enum nativeType
- OrderFilter   -> SortFilter

Add @deprecated notes (ORM + ODM; BackedEnumFilter is ORM-only) pointing at
the replacement. PHPDoc-only, no runtime trigger - the wiring-level triggers
(#[ApiFilter], Operation::$filters) land separately.
