Fix duplicated character input in press_key

[monir600p-blip]

Summary

Fix duplicated text entry for printable single-character keys in press_key().

Problem

press_key() was sending printable characters twice:

• once via Input.dispatchKeyEvent with type="keyDown" and text=...
• again via Input.dispatchKeyEvent with type="char"

That caused helpers like fill_input(...) to duplicate every typed character.

Fix

Only send text on keyDown for non-single-character cases.
Printable single-character input is now inserted by the char event only.

Verification

Verified locally with browser-harness against a real Chrome session:

• fill_input(...) now writes normal text without duplication
• form fields on https://httpbin.org/forms/post were filled correctly
• navigation and page-reading behavior still worked afterward

Summary by cubic

Fix duplicated character input in press_key() by sending printable single-character input via the char event only. Prevents double characters in helpers like fill_input(...) and normal form entry.

• Bug Fixes
  • Skip text on keyDown for single printable keys; keep char event for insertion. Multi-character cases still send text on keyDown.
  • Verified with browser-harness in Chrome: inputs no longer duplicate; navigation and page reading remain unaffected.
