Forbid localStorage access in eslint (#36461)

Followup to
https://github.com/go-gitea/gitea/commit/59f812bc1cc52f15d66d1b233f11e43339c09cec,
enforce using our localStorage wrapper in eslint.

Also did a few tweaks in the eslint config, like removing the incomplete
list of globals, this is a non-issue with typescript.
