fix(web): complete the CSP-build migration across remaining surfaces

- audio reader: scrub/volume/speed/genre-tick bindings converted to
  component methods (onScrubInput, setVolumeFromEvent,
  applyDefaultSpeedFromSelect, volumeLabel, railTickStyle,
  isSkipActive/isSpeedActive) — these used Number/Math/String globals
  that the CSP evaluator cannot resolve
- fmtTime restored to the audioReader component: the unexport pass
  had ripped it from the Alpine.data object (time displays were dead)
- book detail: cover-upload click and banner edit validation moved to
  component methods (triggerCoverUpload, bannerEditHasText)
- admin/docs/index components: init() hooks for their x-init chains
- CSP header: 'unsafe-eval' dropped — the CSP build needs no eval
- e2e spec: replace test.info().annotate (unavailable in this
  Playwright version) with console logging
