Tables button alignment is off on master

[juliushaertl]

This is due to the design change coming with Nextcloud 30.

We probably need to adjust to use the css variables there as well:

@juliushaertl Is there any instruction which css variables should be updated? Is it https://help.nextcloud.com/t/css-variable-change-and-probable-regressions-in-apps/196999?

I'm not sure why the buttons are misaligned, but if there are any hardcoded height or margin/padding values it might be worth to adapt them to css variables.

• height should probably be adapted to --default-clickable-area
• padding/margin either try to align more dynamically with flex layouts or use a multiple of --default-grid-baseline

Also see https://docs.nextcloud.com/server/latest/developer_manual/html_css_design/css.html#css-variables for an overview on css variables and where to use them
