refactor(crud): migrate v2 component usages to field-editor-v3

Replaces all active Element_ae_crud_v2 usages with Element_ae_obj_field_editor_v3,
and direct core_func.update_ae_obj_id_crud_v2 calls with api.update_ae_obj_v3.
Adds 'number' field_type to v3 editor. All on_success callbacks trigger SWR
refresh via events_func load functions so liveQuery updates Dexie correctly.

- element_ae_obj_field_editor_v3: add 'number' input type
- ae_comp__event_session_obj_li: replace core_func v2 API calls + dead import
- ae_comp__event_location_obj_li: migrate 2x Element_ae_crud_v2 (name, description)
- ae_tab__manage: migrate 7x Element_ae_crud_v2 (priority/checkbox, numbers, text, tiptap)
