fix: enable no-deprecated-classes tailwind lint rule (#9417)

## Summary

Enable `better-tailwindcss/no-deprecated-classes` lint rule and auto-fix
all 103 violations across 65 files. First PR in a stacked series for
#9300.

## Changes

- **What**: Replace deprecated Tailwind v3 classes with v4 equivalents:
  - `rounded` → `rounded-sm` (85)
  - `flex-shrink-0` → `shrink-0` (16)
  - `flex-grow` → `grow` (2)
- Enable `no-deprecated-classes` as `'error'` in eslint config
- Update one test asserting on `'rounded'` class string

## Review Focus

Mechanical auto-fix PR — all changes produced by `eslint --fix`. No
visual or behavioral changes (Tailwind v4 aliases these classes
identically).

Fixes #9300 (partial — 1 of 3 rules)
