Fix: Remove single instance lock

[MathCunha16]

This pull request removes the single-instance locking mechanism from the backend and updates the application version to v0.1.17-alpha across all relevant files. The changes simplify the backend startup process by no longer preventing multiple instances from running with the same data directory.

Backend changes:

• Removed the single-instance lock implementation for both Unix (lock_unix.go) and Windows (lock_windows.go), including all related file locking logic. [1] [2]
• Updated main.go to no longer acquire or release the single-instance lock during startup.

Version updates:

• Bumped the application version to 0.1.17-alpha in version.go, package.json, Cargo.toml, and tauri.conf.json for consistency across backend and frontend. [1] [2] [3] [4]

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to ebe6d

The frontend version update is incomplete because the lockfile still identifies version 0.1.12-alpha, which can cause inconsistent install or build metadata. Regenerate or update the lockfile before merging.
