Closes #207.

What

Reverts #195, which had switched TV control (Google TV / Android TV over ADB: turn on, switch to the PC's HDMI input / custom Input command, standby on the way back) off for 1.7. A user confirmed it works on a Coocaa/Skyworth TV, even from deep sleep, with am start -n com.smartdevice.livetv/skyworth.skyworthlivetv.osd.ui.mainActivity.LiveTvScreenActivity as the input command.

• TvControlService.IsAvailable and IsTvControlAvailable are gone; System → TV shows again and ConsoleEngine.Start uses config.Tv as before.
• The tour's System stop mentions TV again (6 catalogs).
• The TV control section is back in the six guides and the feature line in the six READMEs.
• Kept from the revert: the 1.7.0 changelog entry for chore: leave TV control out of 1.7 #195 and the 1.7 "What's new" README lines (history). New [Unreleased] entry in both changelogs.
• PRD: D-26 now records the return; TV-001 ticked. docs/TESTING.md: the chore: leave TV control out of 1.7 #195 checks are replaced by checks for the return (including the custom input command).

Testing

• dotnet test on Linux: 675 passing, 2 failing (PackageLogoTests). They fail the same way on main, so they aren't caused by this PR.
• Build left to CI (Windows only). The TV itself can only be checked by hand: see docs/TESTING.md §3c.
