refactor(tsconfig): enable noUncheckedIndexedAccess

Also took some tips from https://www.totaltypescript.com/tsconfig-cheat-sheet
Not implemented any of the options mentioned, but also
it's worth looking to https://www.totaltypescript.com/typescript-is-coming-to-node-23
to prepare for future Node native TypeScript support.
