Buttons, inputs, selects, pickers, toggles and tabs all declared 34 while
IconButton and the PageHeader action sat at 32, so anything mixing them
in a row was 2px out of alignment.
Everything now reads CONTROL_HEIGHT (32) from constants, so the number
lives in one place instead of nine.
Two content-box fixes were needed to make 32 safe, both measured in the
browser rather than assumed:
- MUI's button line-height is 1.75 - 22.75px at our 13px base - which
with 6px padding needs 34.75px. It was already over its own box at 34
and would have clipped at 32. Now 1.2, which leaves headroom for the
taller scripts we ship (ar, th, vi, ja, zh).
- MUI pads the inner input 8.5px top and bottom, so an input's content
needed 35.7px inside a 32px shell and was being cut off by
overflow:hidden. Padding is zeroed in the theme for both the input and
the Select's div, which centres instead.
Verified in the DOM: button, select and input all render at exactly 32
with scrollHeight equal to height, so nothing is clipped.

Inputs disagreed on both hover and focus. The theme's MuiOutlinedInput
hovered to text.primary - near-black in light mode - while Select,
TextInput and DatePicker each overrode hover back to `divider`, which is
the resting colour, so those had no hover cue at all. Four behaviours
across four components.
Now defined once in the theme and inherited by every outlined input:
rest divider 1.55:1 light / 1.73:1 dark
hover text.disabled 3.64:1 light / 4.66:1 dark
focus primary, 2px 5.93:1 light / 6.36:1 dark
error error.main
The per-component overrides in Select, TextInput and DatePicker are gone,
so there is one place to change this next time.
Focus in dark mode takes primary.light. The brand green is only 2.86:1 on
the dark ground, which made a focused input dimmer than a hovered one.
`main` is deliberately left alone: it is the fill for contained buttons,
and lightening it would flip their label to dark text across 31 sites.
