TASK 4 audio fixes round 2: dB-scaled meters, game bar moved into the preview, Notepad About button replaced by the logo → in-app About — AudioLevelMeter.ToDisplay maps -60..0 dBFS onto 0..1 (real speech/game RMS ~0.01..0.1 linear left the flat scale dead; both meters now scale through it before volume); the game audio bar moved OUT of the footer (back to two rows) and is now a bottom-center dark chip overlaid on the preview window — monitoring UI only, never on the live output; the top-bar About button (opened THIRD-PARTY-NOTICES.txt in the OS viewer) removed, the ytLlive wordmark now opens the in-app About overlay, and task 21 queued (real logo + creator-hub About with premium/coffee/socials links + in-app scrolling licensing panel) — 169 tests passing, 0 warnings
