feat(core): add sub-1x playback rates to defaults

[mihar-22]

Closes #1117

---

Note

Low Risk
Low risk: change is limited to default playbackRates values and corresponding unit test updates, with no security or data-handling impact.

Overview
Adds sub‑1x playback speeds (0.25, 0.5, 0.75) to the default playbackRates list used by the playbackRate feature.

Updates PlaybackRateButtonCore tests to reflect the new rate list, including wrap-around now returning 0.25 and adding coverage for cycling through the new sub‑1x rates and selecting the next greater rate when the current value isn’t in the list.
