Introduces the new Studio section (Source -> Characters -> Voices ->
Perform & Export) that reuses the existing Read Aloud/Library/Script
Rehearsal code via DOM reparenting instead of duplicating it, and rolls up
a long tail of bugs found while producing a real audiobook through it:
umlaut-eating name sanitizers, a voice picker that mispositioned itself and
capped results at 60, PDF pagination silently breaking on trimmed \f
markers, a race letting stale audio keep playing after a new line was
clicked, an alias-overlap bug that could silently redirect a voice/image
save onto the wrong character, voice design failing outright during brief
TTS backend restarts instead of retrying, sparse cast entries defaulting to
English/wrong gender, and a reassigned voice never reaching an already-open
Stage session or invalidating its cached audio. Also adds a persistent
per-line audio cache, audiobook export browsing/download, and an inline
voice-design prompt editor. Full details in CHANGELOG.md.

When a PDF audiobook is cast and saved to the Rehearser, page breaks now
carry the source PDF page number. In the Stage view each divider renders
as "— Page N —" instead of the generic "— Page break —".
Implementation:
- audiobook.js: `audiobookBuildScript()` encodes the page number in the
form-feed line (\fN instead of bare \f) at each page boundary.
- rehearser-parse.js: `parseScript()` now matches `line.startsWith('\f')`
and extracts the trailing page number into `line.page`.
- rehearser.js: `buildScriptPage()` renders "— Page N —" when `line.page`
is set; `toScript()` round-trips the number back (\fN) so it survives
save/reload; `importPDFScript()` also encodes page numbers (\f<pageIdx+1>)
when importing screenplay PDFs directly.
