Add ESLint rule to enforce Lingui msg usage (#9789)

* Add ESLint rule to enforce Lingui msg usage

Adds a custom ESLint rule 'lingui-msg-rule' that ensures the Lingui _()
function is called with msg`` template literals or plural/select macros,
preventing accidental misuse like _('string') which bypasses i18n.

* Support msg({...}) descriptor form and add auto-fix

- Allow msg() function call form: _(msg({message: 'Hello'}))
- Add auto-fix for string literals: _('Bad') -> _(msg`Bad`)
- Add auto-fix for untagged templates: _(`Bad`) -> _(msg`Bad`)
- No auto-fix for variables/function calls (not safely fixable)

* fix complex cases

* run autofix HELL YEAH
