Default Increase / Decrease dont size keybinds conflict logical vs physical layout

[rhodes-b]

Issue Description

Brought up in #8729 and specially this commit d015efc#diff-f0bf2dd599094e0226eb387ce0bf6dffec2fb7c4f61c9ad35fd6efe82a062793

increase font size only works with the physical layout while decrease and reset are using the logical layouts

one of the keybinds needs to change, to me it seems increase font size should change to use logical layout

I acknowledge that:

• I have reviewed the FAQ and confirm that my issue is NOT among them.
• I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.

Thanks for writing this up. I've spawned a PR for it: #8759.

I added #9469 which fixes this, plus the problem with physical bracket keys that prevent #8759 from fixing my problem.

(yay other alternate keyboard users, thanks for helping to fix this!)
