✨ feat: add model name matching rules with priority-based lookup

Add flexible model name matching system to support different matching patterns:

Backend changes:
- Add `name_rule` field to Model struct with 4 matching types:
  * 0: Exact match (default)
  * 1: Prefix match
  * 2: Contains match
  * 3: Suffix match
- Implement `FindModelByNameWithRule` function with priority order:
  exact > prefix > suffix > contains
- Add database migration for new `name_rule` column

Frontend changes:
- Add "Match Type" column in models table with colored tags
- Add name rule selector in create/edit modal with validation
- Auto-set exact match and disable selection for preconfigured models
- Add explanatory text showing priority order
- Support i18n for all new UI elements

This enables users to define model patterns once and reuse configurations
across similar models, reducing repetitive setup while maintaining exact
match priority for specific overrides.
