fix: Telex mode broken — is_vn_control_key consumed normal letters a/e/o/d/u

Only pure control keys (f,s,r,x,j,w) should be consumed silently.
Base letters used in double-letter marks (aa→â, ee→ê, etc.)
are normal typing keys that must be forwarded when no mark triggers.
Removed uppercase variants too — consolidated with to_ascii_lowercase().
