Additional linear tweaks (#8375)

- Textareas have a fixed (larger) height. This was requested by design
and I thought I fixed it while back.

- Since the typeform survey popover doesn't work well on mobile, the
button will instead open the survey in a new tab for mobile users.
- Workaround for the first linear output on local not being
automatically selected for display
- Add the linear mode toggle to the bottom left of mobile layout

- Adds a hamburger menu to the mobile layout providing buttons for
opening workflows, templates, and an additional exit linear option.
- Button takes up a full line of space, so it doesn't provide much space
savings currently. May need some design iteration.

And an unrelated tweak requested by Comfy: when opening templates, the
searchbar is autofocused.
