fix(avc): align scaled capture dimensions to encoder alignment

[gmegidish]

Summary

(display * scale).toInt() can produce odd dimensions — Pixel 10 Pro's 1080x2410 display at scale 0.5 yields 540x1205 — which isSizeSupported() rejects, killing the capture before any frame with the misleading "exceed codec capabilities. Maximum supported: 3840x3840" error. In production this makes WebRTC streaming fail 100% of the time on any device model whose scaled height is odd (verified live on a farm Pixel 10 Pro: scale 0.50 always fails, scale 0.48 with even dims streams fine).

Fix: query the encoder's widthAlignment/heightAlignment (min 2) and round each scaled dimension down to it before validating/configuring.

Walkthrough

streamAvcFrames now creates the AVC codec before calculating scaled dimensions. It reads the codec alignment requirements and rounds scaled width and height down to compatible values. If the resulting dimensions are invalid, it releases the codec before throwing an exception. The previous warning for odd dimensions was removed.
