Rewrites the PostType component and its styles to match the voice-
message visuals from Mattermost mobile.
Before / after screenshots in docs/voice-mobile.png and docs/voice-web.png.
Changes:
- webapp/src/components/post_type/post_type.jsx
* Use React.createRef() for the <audio> element instead of
document.getElementById after mount.
* Custom div-based scrubber with track / fill / floating thumb,
replacing the native <progress> element.
* Mouse + touch drag-to-seek support (touch-action: none on the
scrubber and passive: false on touchmove so we can preventDefault).
* Time-display logic: shows total duration before first playback,
current time afterwards.
* Adds ARIA attributes to the scrubber (role=slider, valuemin/max/
now) and aria-label to the download link.
- webapp/src/components/post_type/post_type.css
* 44px circular play button with theme-accent tinted background.
* Horizontal scrubber with 4px track and 14px floating thumb.
* Tabular-nums duration text.
* Download icon. Theme colors are derived from the existing theme
tokens (buttonBg / linkColor, centerChannelColor, centerChannelBg).
No new dependencies. No backend changes.
Tested on Mattermost server 10.11.0 (web — Chrome + Safari). Confirmed:
play/pause, click-to-seek anywhere on the scrubber, drag-to-seek
(mouse and touch), time display flipping between duration and current
time, download link, theme adaptation when the user switches themes.

A companion PR (#67) is the small bug-fix that makes voice messages renderable on Mattermost mobile (by setting
file_idson the post). This PR is independent and can be merged separately in either order — whichever lands second only needs a smallpost_type.cssrebase since both touch that file.
