feat(playback): global speed with three strategies (#852)

* feat(playback): global speed with three strategies

Add Settings → Audio and player-bar controls for global playback speed
(speed with auto pitch correction as default, varispeed, manual pitch shift).
Time-stretch runs on a background worker; Orbit sessions force 1.0× passthrough.

* fix(playback): align seekbar, seek, and progress on content timeline

Unify UI timebase across varispeed and preserve strategies: full-track
duration, speed-scaled progress for DSP paths, and content-timeline seeks
without varispeed scaling. Reset the sample counter after seek so clicks
land correctly; restart playback on strategy/enable changes instead of
fragile hot-switching.

* fix(ui): anchor playback speed popover like volume controls

Replace the centered EQ-style modal with a player-bar popover (outside
click, Escape, reposition on scroll). Show compact controls in the bar
and overflow menu; keep strategy hints and labels in Settings only.

* docs(release): CHANGELOG and credits for playback speed (PR #852)

* docs(changelog): add playback speed entry for PR #852

* fix(clippy): simplify raw_counter_samples branch for CI

Collapse duplicate if branches flagged by clippy::if-same-then-else.

* fix(ui): wheel on pitch slider adjusts pitch in speed popover

In compact player-bar controls, scroll over the pitch row changes pitch;
elsewhere in the panel changes speed. Stop propagation so overflow menu
wheel does not tweak volume.

* fix(playback): address PR #852 review and drop ineffective dynamic imports

Translate playback-rate strings for de/fr/es/zh/nb/nl/ro; restamp sample
counter on live preserve-path speed changes; use neutral rate atomics for
radio progress; static-import playerStore in playListenSession (move preview
volume sync to previewPlayerVolumeSync side-effect module).

* fix(i18n): translate playback-rate strategy labels in all locales

Replace leftover English Varispeed/Pitch strings in ru and other non-en
settings blocks so popover strategy buttons and hints read natively.

* fix(i18n): refine German varispeed label to "Tonhöhe folgt dem Tempo"
