feat(record-inputs): tap-to-adjust steppers + inputmode keypad hint

Adds [-] / [+] buttons around every numeric input in the Record Inputs
dialog (single-value, dual-entry, and pass_fail+range branches). Tap
to increment / decrement by the recipe-author-derived step size
(stepFor() already computes this from target_min/target_max precision,
falling back to input-type defaults).

- Decrement clamps at 0 (typical qty/time/temp on a plating floor
  doesn't go negative; if needed, operator can still tap the input
  and type a negative value)
- Increment uses _stepRound() to avoid floating-point fuzz on decimals
- Center-aligned monospace-ish input between the buttons for clarity
- inputmode='decimal' (or 'numeric' for time fields) hint so when the
  operator does tap the input, the iPad shows a number keypad instead
  of the full keyboard

Touches single-value, dual-entry (min/max), and pass_fail+range. Other
multi-field widgets (multi-point thickness, bath chemistry panel) still
use plain inputs — separate request if they need steppers too.
