refactor(packages): consolidate 3 feedback packages into @manacore/feedback

Merged shared-feedback-types + shared-feedback-service + shared-feedback-ui
into a single @manacore/feedback package. Updated imports in all 21 apps.

Before: 3 packages (types, service, ui) with cross-dependencies
After:  1 package with direct imports, no circular refs

Note: ESLint warnings from pre-existing unused vars in chat/mukke
servers are unrelated to this change.
