Rebrand to Offscale and rework the panel header

Forked from omarchy.tailscale at the packaged commit (omarchy-dev
4.0.0.r1744.gf002044). The `tailscale` branch holds the pristine upstream
subtree history so upstream changes can still be merged in; `master` is
this fork.

- Rename the plugin to pastilhas.offscale: manifest id/name, moduleName
  and ipcTarget, and display strings. Deliberately NOT renamed: the
  lowercase "tailscale" CLI invocations, the TailscaleIPs/TailscaleIPv6
  JSON fields from `tailscale status --json`, and
  authorizeTailscaleOperator. Renaming those loads fine but silently
  breaks peer parsing.
- TailscaleIcon.qml -> OffscaleIcon.qml, now rendering offscale-logo.png
  instead of the 3x3 dot grid, keeping the crossed/warning states.
- Add OffscaleHero.qml: a copy of qs.Ui.PanelHero with a titleComponent
  slot, so the wordmark (offscale-text.png) can replace the title text.
  Otherwise byte-identical to the original, so it stays diffable.
- Drop the cycling hero phrases entirely - the array, the 2.8s timer and
  the metaOpacity fade.
- Show the local machine as a PeerRow of its own, so it gets the same
  layout and copy menu as tailnet peers. Adds `navigable` to PeerRow so
  that row stays out of the peers keyboard cursor.
- Enlarge the bar icon: BarIconButton pins its icon to opticalCanvas, so
  opticalSize/slotSize are overridden alongside iconSize.
