PDF.js TextLayer renders <br> between text spans for visual line wrapping.
The TTS SSML generator was converting these to <break> elements, causing
TTS engines to pause at every PDF line break within paragraphs. Fix by
rejecting <br> (along with canvas and annotationLayer) via the node filter
when the document is detected as a PDF.

The `pages` getter used Math.ceil(viewSize / containerSize) which inflates
the count by 1 when floating-point drift makes the ratio slightly above an
integer (e.g. 4.00000001 → 5). Use Math.round to absorb sub-pixel drift,
matching the approach already used in #getPagesBeforeView.

Closes#3770.
Add transformStylesheet rule that clips CSS width declarations exceeding the
viewport with max-width and border-box sizing. Also add @testing-library/react
to vitest browser optimizeDeps.include to prevent mid-test Vite reloads on CI.

Two issues caused embedded EPUB fonts to fail:
1. Adobe font deobfuscation (http://ns.adobe.com/pdf/enc#RC) derived the
XOR key from the wrong UUID. getUUID() picked the first UUID across all
dc:identifier elements (e.g. Calibre's internal UUID) instead of the
book's unique-identifier. Also fixed getElementById not working on
DOMParser-parsed XML (no DTD), and made UUID regex case-insensitive.
2. transformStylesheet replaced generic font families (sans-serif, serif,
monospace) with CSS var() references without fallback values. In
fixed-layout iframes where setStyles doesn't inject the variables,
the undefined var() invalidated the entire font-family declaration
per CSS spec, causing all fonts to fall back to system defaults.
