Promote dev to staging

[patrickrb]

Promote latest dev to staging (cuts an android-dev.<run#> prerelease + Play internal upload).

Included since the last promotion (#321)

• Fix Play rollout rejection: bump versionCode offset (Fix Play rollout rejection: bump versionCode offset past pre-split run numbers #322) — restores the staging→internal Play upload. The CI split reset GITHUB_RUN_NUMBER (780 → 167); the + 1000 offset now clears the historical max, so this promotion's internal upload should complete instead of being rejected with "does not allow any existing users to upgrade."
• Improve RX decode sensitivity: deep decode default, level meter, FIR downsample (Improve RX decode sensitivity: deep decode default, level meter, FIR downsample #319)
• Make dropped USB TX cycles and reinit timing legible in debug.log (Make dropped USB TX cycles and reinit timing legible in debug.log #320)
• Fix POTA Nearby parks showing far-away regions (bad upstream centers) (Fix POTA Nearby parks showing far-away regions (bad upstream centers) #317)
• Fix POTA park picker sheet not opening (tap does nothing) (Fix POTA park picker sheet not opening (tap does nothing) #316)
• Address Copilot review on Promote dev to staging #321: deep-decode loop budget + capture allocation

Pull request overview

Promotes the latest dev branch to staging, producing an android-dev.<run#> prerelease and attempting a Play internal upload, while pulling in the most recent functional changes (decoder sensitivity, POTA picker/nearby logic, USB logging, and USB capture DSP).

Changes:

• Fix Play internal-track rollout rejection by increasing the CI-derived versionCode offset (GITHUB_RUN_NUMBER + 1000).
• Improve decode sensitivity/observability: deep-decode defaults + slot-scaled loop budget, RX input-level meter, and clearer USB TX/capture logging.
• Fix POTA park picker UX and nearby-park correctness/perf (overlay hosting, broader candidate set, concurrent fetch, distance cap).
