refactor: remove unused optional props and arguments in apps/web

[JonasBa]

Hey folks, I'm working on an experimental CLI which uses the tsgo toolchain to find optional component and function signatures that are in practice never passed. This is essentially dead code elimination, and a complementary workflow to run alongside a tool like knip.

The changeset in this PR has been done using the script as the reporting tool, and an agent validator loop walking through each reported line one by one to first inspect the report, analyze the call sites, removing them, and later re-running ts. If done correctly, the code that has been removed should have been effectively dead.

The reporting script heavily relies on type quality and only reports on types whos members are statically enumerable.

Scope notes:

• Only apps/web is touched. Findings in shared packages/* were excluded because they can have consumers outside this project's typecheck graph (platform atoms, API apps, embeds).
• Two components were deliberately left alone and may deserve maintainer attention instead: CalendarListContainer (its heading/fromOnboarding props are never passed, which means the component currently renders null on both of its call sites) and LimitedBadges (maxVisible is never passed, so the visible/hidden split degenerates).

I'm opening this PR in an effort to help you eliminate dead code, but also to gain feedback on the script and the detection mechanisms. There are always risks of false positive reports, and removal of code that is actually still required at runtime.

Some references of PRs opened to other repositories that have been merged or are still open:

⏳ Sentry (followup 1k loc removed)

⏳ npmx
⏳ Signal Desktop

Would love to hear your feedback 🙏🏼
