chore(lint): convert type aliases to interfaces (autofix)

- Remove no-use-before-define rule (conflicts with unistyles ordering)
- Add typescript/consistent-type-definitions: interface
- Run oxlint --fix: 606 type->interface conversions across 268 files

Typecheck green. Warnings: 5432 -> 3787 (-1645).
