chore: add dart:format, prettier:format and mise:format tasks

Splits the single `format` task into three named sub-tasks:
- `dart:format` — dart format . (use --no-deps for speed after Dart changes)
- `prettier:format` — Prettier for JS/TS/MJS files
- `mise:format` — mise fmt for mise.toml

The top-level `format` task now depends on all three. CI check
formatting step expanded to cover all three. Prettier added to root
package.json; .prettierignore excludes build/, android/, ios/.
