Fix regional keyboard input (German and other layouts)

[zortos293]

Summary

Fixes incorrect and missing keys when using non-US keyboard layouts (e.g. German QWERTZ with English in-game language), as reported in #330.

Aligns OpenNOW keyboard handling with the official GFN web client:

• Send layout-aware virtual keys from event.keyCode instead of US physical event.code
• Send scancode: 0 on live key events (official client does not forward set-1 scancodes)
• Match per-key modifier encoding (yS) and sync Caps/Num/Scroll via lock-key packet (type 19)
• Lock fullscreen keys intercepted by the browser (KeyT, KeyN, etc.) so shortcuts reach the stream

Closes #330

Test plan

• Set keyboard layout to German (de-DE) in OpenNOW settings
• Stream a session and verify n, T, ö, ü, +, #, and related keys type correctly
• Repeat on web and native streamer modes
• Confirm Escape still works to exit pointer lock / overlay

💡 Codex Review

OpenNOW/opennow-stable/src/renderer/src/gfn/inputProtocol.ts

Lines 469 to 471 in 2f2b5d5

	const keyCode = event.keyCode;
	if (Number.isInteger(keyCode) && keyCode > 0 && keyCode !== 229) {
	return keyCode;

Preserve side-specific modifier VK mapping

Route KeyboardEvent values through virtualKeyFromKeyCode() before returning, instead of returning raw event.keyCode immediately. In Chromium/Electron, right-side modifiers commonly report generic keyCodes (e.g. ShiftRight as 16), so this early return drops the existing event.code-based mapping to VK_RSHIFT/VK_RCONTROL/VK_RMENU and collapses left/right modifier identity. That can break shortcuts and AltGr-dependent input paths on non-US layouts.

Keep generated locale files out of feature commits

Revert manual edits to non-English locale outputs in this feature change. Per /workspace/OpenNOW/AGENTS.md, only locales/en.json is the source of truth and other locales/*.json files are Crowdin-generated; changing them here creates translation drift and noisy overwrite/conflict risk on the next Crowdin sync, which hurts maintainability and release reliability.
