blink_cursor = false doesn't prevent blink from application escape codes

[sporteka2]

Environment

• mlterm 3.9.3 (Ubuntu 24.04)
• X11

Problem

Setting blink_cursor = false in ~/.mlterm/main does not prevent cursor blinking when an application sends escape sequence \E[?12h (DECSET bit 12 — cursor blink enable).

Other terminals (kitty, alacritty, wezterm) respect their own cursor blink setting and ignore \E[?12h from the application.

Steps to reproduce

1. echo "blink_cursor = false" >> ~/.mlterm/main
2. Start mlterm
3. Run printf "\e[?12h" (or an application like opencode that sends this sequence)
4. Cursor starts blinking despite blink_cursor = false

Expected behavior

With blink_cursor = false, the cursor should never blink regardless of escape codes sent by applications.

Suggestion

How can I completely disable cursor blink in mlterm so that application escape codes like \E[?12h are ignored?
