What does this PR do?

Removes 3 @calcom/web imports from @calcom/features by moving the blocklist UI components and useEvent/useScheduleForEvent hooks into apps/web/modules/, and removes 4 dead type imports from packages/features/bookings/Booker/types.ts.

Why this matters

• Fixes a silently broken import: useEvent in packages/features imported useSchedule via "~/schedules/hooks/useSchedule" — which only resolved because apps/web's tsconfig maps ~ to modules/*. Under packages/features' own tsconfig (~ → ./*), the file doesn't exist. The typecheck CI never caught this because packages/features has no type-check script; it's only checked transitively through apps/web's tsc, which applies the wrong path alias.
• Enforces package boundaries: useEvent depends on @calcom/trpc/react, which belongs in apps/web/modules/, not packages/features. The blocklist components similarly depend on web-only imports (~/data-table/components).
• Removes dead code: 4 unused type imports removed from packages/features/bookings/Booker/types.ts (including a @calcom/trpc import).

No runtime behavior change.

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. N/A — no docs changes needed.
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

Build verification only — no functional changes. Confirm the app builds and the affected views (blocklist admin, org privacy/blocklist, booker, embed) render correctly.
