fix(test): Improve UDP tests, super flash and sparse handling

Refactor tests and driver behavior:

- FastbootCLI: remove the unused --force flag and related variable/help text.
- Tests (UdpTransportTests): make UDP timeouts/attempts configurable via env vars, enable SO_REUSEADDR when binding test sockets, harden CompleteHandshake with proper packet handling and timeout handling, wrap flaky tests with a RunWithRetries helper, and restructure server/transport lifecycles to avoid port conflicts and race conditions.
- InternalFlashSparseFile: materialize Resparse() results with ToList() to avoid deferred enumeration issues.
- FastbootDriver: add using for sparse core, suppress verbose step notifications for sparse/flashing steps, add an overloaded FlashImage supporting super-partition optimization and a progress callback; implement AOSP-style super optimization path (uses SuperFlashHelper) while allowing disabling of the optimization.
- Project: bump FirmwareKit.Sparse package from 1.0.1 to 1.0.2.

These changes improve test stability, add a super-partition optimization pathway, and fix potential runtime enumeration and race issues.
