Hide tagline, version tag, and Phone Setup on narrow viewports so
the header stays single-row: logo + status dot + blocking toggle.
Reduces logo font-size from 1.8rem to 1.4rem on mobile.
Closes#108.
- Add `version` field to /stats (from CARGO_PKG_VERSION).
- Show `v0.13.1` next to the Numa wordmark in the dashboard header.
- Restructure the footer into two semantic rows:
Row 1 (paths): Config · Data · Logs (platform-detected)
Row 2 (runtime): Upstream · DNSSEC · SRTT · GitHub
- Drop Mode from the footer (redundant with Upstream label).
- Show only the matching-platform log path instead of both
macOS and Linux unconditionally.
