fix: tidy the About tab family row and privacy note

[jatinkrmalik]

Summary

• Replaced the About tab's raw family URLs with the same ghost icon buttons as Talk to us.
• Family icons are all ink currentColor marks (platform SVGs from the brand book, HQ mic, 1U chassis). The host card uses the official tower mark.
• "Keep this host private" is a mint info box instead of a left-rule callout.
• License and Version share a baseline. The footer is just a centered copyright line.

Verification

• uv run ruff check on the touched Python files, ruff format, and pytest tests/test_about.py tests/test_admin.py tests/test_build_info.py
• Full just test (lint, mypy, package, unit, compose)
• Browser-checked About at 1440, ~1024, and 390, plus dark theme
• Container build, if Dockerfiles or lockfile changed
• Docs updated for setup, network, or configuration changes

Privacy and security

• No secrets, recordings, transcripts, or private hostnames added
• No weakening of bearer auth, upload limits, retention, or default binding without discussion

Greptile Summary

The PR refreshes the About tab’s family links, host branding, privacy notice, build facts, and footer presentation.

• Replaces raw family URLs with labeled ghost buttons and vendored brand marks.
• Uses the tower artwork for the host card and a mint information box for the privacy warning.
• Simplifies the footer and adds focused markup, styling, and asset tests.

Confidence Score: 5/5

The PR appears safe to merge with no actionable defects identified.

The new SVG assets are included by supported packaging paths, the labeled links remain accessible, and the existing wrapping layout accommodates the expanded family row.
