lint: move last remaining native eslint rules to oxlint (create new alternatives) (#6468)

* lint: clean up unnecessary config and disables

* fix: update package import path in browser preload script

* lint: create custom ESLint rules for rules not in oxlint

- Add object-shorthand-properties rule (replaces object-shorthand)
- Add prefer-const rule (replaces prefer-const)
- Add no-anchor-tag rule (replaces no-restricted-syntax for <a> tags)
- Add no-react-default-import rule (replaces no-restricted-syntax for React.*)

These custom rules are needed because oxlint doesn't support these rules yet.
All rules are properly tested and integrated into the ESLint config.

* refactor: enhance prefer-const rule to track variable reassignments by scope

- Introduced a mapping of scopes to reassigned variable names, improving the accuracy of the prefer-const rule.
- Added helper functions to determine variable scopes and reassignment status.
- Updated logic to check variable reassignments during declaration analysis.
- Adjusted test cases to reflect changes in variable handling.
