i18n(admin,settings): copy consistency sweep

Several smaller A8 copy nits in one pass:

- Notifications settings subtitle no longer hard-codes "Telegram,
  ntfy, Web Push" — the channel-reliability board only shows
  configured channels, so naming all three made one of them look
  missing.
- Admin /feedback page subtitle widened to "feedback, bug reports,
  and feature requests" so it matches what the inbox actually
  contains; the duplicate card-level title + description on
  /admin/feedback is gone (page header already provides them).
- /admin/services subtitle now mentions integrations alongside
  notification channels (the API and moodLog toggles live there
  too); per-row "system-wide" suffixes dropped — the section
  subtitle already establishes the scope.
- /admin/ai-quality subtitle reads as a sentence instead of the
  jargon "(severity x provider)" expression.
- /admin/feedback empty state is "All caught up" / "Alles erledigt"
  instead of the English-idiom "Inbox zero".
- /achievements subtitle rewritten in both EN + DE to drop the
  dev-speak "from feature rollout onward".
- /admin/api-tokens permission badges show "All" (with a tooltip)
  instead of the bare regex glob `*`.
- Brand spelling normalized: every Glitchtip → GlitchTip.
