🔍 feat(edit-token): add search capability to model limit selector

Changes:
• `Form.Select` for “Model Limits” now supports in-dropdown searching (`filter` + `searchPosition='dropdown'`) enabling quick model lookup.
• Removed `maxTagCount` to display all selected models without truncation.

Benefit: simplifies selecting specific models when the list is large, improving usability during token creation/editing.
