refactor(tsconfig): remove redundant options and rely on modern defaults

- removed unnecessary `lib` entries
- removed explicit `module: ESNext` (now default)
- removed `useDefineForClassFields` (implied for ES2022+ / ESNext targets)
- removed `strict` (enabled by default)
- removed `noImplicitThis` (covered by strict)
- added `noUnusedParameters`
- removed `allowSyntheticDefaultImports` and `esModuleInterop` (enabled by default)
- removed `forceConsistentCasingInFileNames` (enabled by default)
