fix: Enable Lingui recommended rules and fix all translation violations (#14133)

- Enable lingui/no-single-variables-to-translate and all other
recommended Lingui rules
- Fix single variable translation patterns (t`${variable}` → variable)
- Fix expression-in-message violations by extracting variables
- Fix t-call-in-function violations by moving translations inside
functions
- Update ESLint configs to use linguiPlugin.configs['flat/recommended']
- Clean up unused imports and improve translation patterns
