- Extract a shared BaseModelPicker (search, keyboard navigation,
filename-based suggestions, dynamic API models such as MiniMax H3
under 'Other (API)') used by both the single-model metadata modal
and the bulk base model modal
- Rework the bulk base model modal into a dedicated inline-list
layout: fixed modal size, sticky-free footer with app-standard
modal-actions/primary-btn/cancel-btn buttons, and an inline option
list that scrolls itself instead of an overlay dropdown covering
the footer
- Selecting an option in change mode now filters the list to the
selection instead of resetting and scroll-jumping to it
- Restore opaque sticky section headers in the bulk modal so scrolled
items no longer bleed through
