Refactor upload and polling logic

This commit consolidates the upload and polling functionalities into a
single `ServerSync` worker. The `oneliner_poller` and `uploader` modules
have been removed, and their responsibilities are now handled by
`server_sync`.

The `ServerSync` worker manages both uploading pending recordings and
polling the `/api/oneliners` endpoint. Uploads take precedence, and
polling only occurs when the pending upload directory is empty. The
worker now uses a unified HTTP client and a single `tokio::select!` loop
for managing these tasks.

Key changes include:
- Removal of `oneliner_poller.rs` and `uploader.rs`.
- Introduction of `server_sync.rs` and `upload.rs` in
  `doctate-client-core`.
- `ServerSync` now handles upload events (`UploadEvent`) and provides a
  `WorkerSnapshot` for UI feedback.
- Upload logic has been refactored to handle transient and terminal
  errors more robustly, including file deletion for terminal failures.
- Polling logic is integrated into the `ServerSync` loop, utilizing the
  existing `SnapshotCache` and `CaseStore`.
- The `App` component in `client-desktop` has been updated to use
  `ServerSync` instead of the separate poller and uploader.
- Documentation comments have been updated to reflect the new structure.

//! Unified client-side worker that owns the only outbound HTTP channel:
//! it uploads pending recordings and polls `/api/oneliners` from a single
//! `reqwest::Client`, in a single `tokio::select!` loop.
//!
//! Design constraints (see plan `berpr-fe-den-plan-lively-journal.md`):
//!
//! - **Uploads have priority.** If anything sits in `pending/`, the worker
//! uploads it; polling happens only when the directory is empty.
//! - **Disk is the queue.** No in-memory `VecDeque` — the worker scans
//! `pending/` at the top of every iteration. FIFO via `recorded_at`.
//! - **Kick channel, no payload.** `notify()` on the handle just wakes
//! the `select!` sleep; the next iteration finds the fresh file on
//! disk.
//! - **Backoff is a local `Duration`.** Exponential, resets on success,
//! capped at `MAX_BACKOFF`. Not persisted across restarts.
//! - **Terminal upload failures delete the file.** 401/413/etc. will
//! never succeed; keeping the audio around would violate the
//! data-minimization rule.
