fix(brand): capitalize "Punktfunk" in user-facing text

The docs site's page title read "punktfunk docs". Fixed that and swept the
rest of the tree for the same defect, capitalizing the brand wherever it is
shown to a human and leaving it lowercase where it is a technical identifier
(CLI/package names, `punktfunk://` scheme, PnP enumerator, TLS SNI, logcat
tag, config paths, CMS tenant id).

User-visible fixes:

- docs-site: page title -> "Punktfunk Docs"; API reference title, meta
  description and the branded bar's aria-label; the BrandMark/Wordmark SVG
  accessible names (the web console already had these capitalized -- the
  docs site had drifted from it).
- Android: six strings of live UI copy -- the local-network permission
  dialog (x2), the connect-screen error banner, and the no-controller
  explainer.
- Apple: the "No Hosts" empty-state text and the fallback display name for
  a host that advertises no instance name.
- Windows client: the `--discover` progress line.
- KWin fake-input: the application name passed to `authenticate()` (the
  grant is cached per-exe, so the string is display-only).
- THIRD-PARTY-NOTICES: fixed in both generators (about.hbs and
  gen-third-party-notices.py) and applied to the three checked-in outputs
  so they match what a regeneration now produces.

Every changed line differs from the original only by letter case, so line
lengths are unchanged and no formatter width rule is affected.
`cargo fmt --all --check` passes.
