Kyle Carberry 500fc5e2a4 feat: polish model config form UI (#24047) ...

Polishes the AI model configuration form (add/edit model) with tighter
layout and better input affordances.

**Frontend changes:**
- Replace "Unset" with "Default" in select dropdowns to communicate
system fallback
- Show pricing fields inline instead of behind a collapsible toggle
- Use flat section dividers (`border-t`) instead of bordered fieldsets
- Move field descriptions into info-icon tooltips to fix input
misalignment
- Add InputGroup adornments: `$` prefix + `/1M` suffix on pricing,
`tokens` suffix on token fields, `%` suffix on compression threshold,
range placeholders on temperature/penalty fields
- Shorter pricing labels (Input, Output, Cache Read, Cache Write)
- Compact JSON textareas (1-row height, resizable)
- Smart grid layouts by field type (3-col provider, 4-col pricing, 3-col
advanced)
- Boolean fields render as a segmented control (Default · On · Off)
instead of a dropdown

**Backend changes:**
- Add `enum` tags to OpenAI `service_tier`
(`auto,default,flex,scale,priority`) and `reasoning_summary`
(`auto,concise,detailed`) so they render as select dropdowns instead of
free-text inputs
