feat(apps): add missing help, feedback, profile, themes, auth pages for cross-app consistency

New pages created:
- Help: citycorners, matrix (with i18n help content)
- Feedback: citycorners, matrix, photos, planta, questions
- Profile: citycorners, mukke, photos, planta, questions, todo, zitare
- Themes: citycorners, photos, planta, questions, zitare
- Forgot-password: citycorners
- Reset-password: citycorners, picture, storage

PillNavigation updated in all 18 layouts:
- helpHref, profileHref, themesHref, feedbackHref consistently set
- Dependencies added (shared-profile-ui, shared-theme-ui, shared-feedback-ui)

All 17 standard apps now have: help, feedback, profile, themes, settings,
forgot-password, reset-password, offline pages. Matrix excluded for profile/themes/auth
(uses own Matrix protocol auth).
