docs(web-ui): fix Stats/Peers/Settings tab-strip miscategorization

argus review on hyperhive#2986: the README listed Stats/Peers/Settings
alongside Permissions/Schedules as dashboard tabs. Checked the actual
frontend rather than trusting dashboard.md prose (which is internally
inconsistent on this - some section headers say "tab" for things that
turned out not to be):

- stats.html and settings.html are real separate bundles
  (frontend/packages/dashboard/src/{stats,settings}.{html,js}) - same
  shape as builds.html/core.html/logs.html, moved to the "own page"
  list.
- Peers is neither a tab nor a page - swarm.js::renderPeerHives
  confirms it is a card list rendered inside the SW4RM tab
  (#peers-block/#peers-section), gated on state.peer_hives being
  non-empty. Folded into the SW4RM bullet instead of listing it as its
  own item anywhere.

The dashboard tab strip is genuinely just four: SW4RM, Y3R C4LL,
P3RM1SS10NS, SCH3DUL3S.
