v2.19.1

Web Terminal

• Clear button now drops server-side history: previously only cleared the visible UI; on reconnect/refresh the old ring buffer would replay
  • New REST endpoint GET /terminal_clear resets the ring buffer (writePos/wsSentPos to 0)
  • Frontend awaits server clear, then _xterm.reset() for a clean state (cursor at 0,0, SGR reset)
• Keyboard shortcuts in view-only mode: standard browser-like behavior when input is disabled
  • Ctrl+C / Ctrl+Insert — copy selection to clipboard
  • Ctrl+A — select entire scrollback
  • In input mode all keys pass through unchanged (Ctrl+C → SIGINT to UART)
  • Implemented via attachCustomKeyEventHandler — xterm scrollback navigation (PageUp/PageDown) preserved
• Clipboard works over HTTP: Copy button and keyboard shortcuts now work when ESP is accessed by local IP (non-secure context)
  • navigator.clipboard requires HTTPS/localhost — added fallback via document.execCommand('copy')
• Unified clipboard helper: all copy paths (terminal, logs, crash log) now go through Utils.copyText in utils.js — single implementation, no duplicate fallbacks
• Terminal Copy / Save: trim trailing empty lines from xterm's virtual buffer (selectAll previously included filler rows beyond actual content)
