fix: Add Linux ozone platform switch for improved compatibility

[jeanfbrito]

• Introduced a command line switch for Linux to set the ozone platform to 'x11', enhancing compatibility with specific environments during Electron startup.

We will be forcing X11 for now until we get a stable Wayland support. This was happening already on older versions of Electron.

Closes #3154

Walkthrough

Adds a Linux-only Chromium startup flag (ozone-platform=x11) at app initialization, adds executableArgs: ["--ozone-platform=x11"] to the Snap build config, and bumps package version from 4.10.0 to 4.10.1. No other control-flow changes.

Changes

Cohort / File(s)	Summary
Linux Chromium configuration src/app/main/app.ts, electron-builder.json	src/app/main/app.ts: on Linux, appends Chromium switch ozone-platform = x11 via app.commandLine.appendSwitch during startup. electron-builder.json: adds executableArgs: ["--ozone-platform=x11"] under linux.snap.
Version bump package.json	Increments project version from 4.10.0 to 4.10.1. No functional changes.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Check app.commandLine.appendSwitch is invoked before any Chromium/Electron initialization that depends on ozone.
• Verify electron-builder.json placement and JSON schema for executableArgs in the linux.snap section.
• Confirm package version bump aligns with release metadata (changelog/release pipeline).

"I twitch my nose and tap the key,
On Linux I flip ozone to X11,
A small hop, a gentler start,
Screens awake and errors part. 🐇"
