Fix remaining UX inconsistencies: eyebrow, duplicate headings, delete confirm

EYE1 + NAME1: Notifications page
- Remove "Operations" inline eyebrow paragraph
- Rename "Notification Operations" → "Notifications" to match sidebar label

DUP1: Remove "Channels" h2 from Notifications tab panel (tab label suffices)
DUP2: Remove "Users" h2 from Identity & Access tab panel (tab label suffices)

DEST2: Notifications channel delete confirmation
- Replace unguarded deleteChannel() with confirmDeleteChannel() + app-confirm-dialog
- Confirmation message names the channel being deleted
