Eslint update 2 (split part 1)

[MomoRazor]

This is a PR cherry picking the simplest changes from this PR in an effort to help decrease the review load needed for Eslint 9 here. This PR include changes which I believe need minimum review effort, as mostly remove syntactic sugar which is no longer recommended by Eslint, with actual conditionals.

If any of the new logic here has any effect, then it is an affect that the system was already suffering from in all likelyhood.

@pylipp let me know if this helps or if I should attempt to split it up further! This is planned to be part 1 of 3 :)

Pull request overview

Cherry-picks low-risk code changes to prepare for ESLint v9 migration, primarily by replacing discouraged TypeScript/JS patterns (non-null assertions, Boolean/String boxed types, @ts-ignore, etc.) with more explicit/ESLint-friendly alternatives.

Changes:

• Replace @ts-ignore with @ts-expect-error (with rationale) in several places.
• Reduce non-null assertions and boxed primitive types (Boolean/String) across FE + statviz.
• Minor conditional/optional-chaining adjustments to satisfy newer lint rules.
