feat(versions): add View all local versions button to model versions tab

Clicking the button closes the modal, writes filter params to sessionStorage,
and reloads the page to show all local versions of the model as individual
cards (bypassing group-by-model dedup). The filter respects the update flag
strategy and the versions-filter-toggle state (same-base vs all versions).

Supporting changes:
- sessionStorage keys vlm_model_id / vlm_model_name / vlm_base_model
- BaseModelApiClient._addModelSpecificParams adds civitai_model_id param
- LoraApiClient calls super._addModelSpecificParams for VLM detection
- LorasControls / CheckpointsControls clearCustomFilter checks VLM first
- PageControls.checkVlmFilter shows customFilterIndicator with label
- Backend parses civitai_model_id, filters before group_by_model dedup
