fix(ux): mobile polish — inputMode=decimal default, dialog padding, more-sheet touch targets

Three audit-pass-#3 mobile findings, all in shared primitives so the
fix lands everywhere those primitives are used.

- Input defaults inputMode='decimal' when type='number' and the caller
  hasn't overridden. Currency/dimension/price fields across invoices,
  expenses, berth specs etc. now show iOS's numeric pad instead of full
  QWERTY. Caller can still pass inputMode='numeric' for integer-only
  fields.
- DialogContent: padding tightens to p-4 on mobile and restores p-6
  at sm+ — the previous fixed p-6 ate ~48px of horizontal width on a
  390px iPhone, crushing form-field space. Also adds a max-h-[100dvh]
  + overflow-y-auto so long modal forms scroll inside the dialog
  instead of pushing the close button off-screen.
- MoreSheet (mobile bottom-tab "More" drawer): grid-cols-3 cells now
  enforce min-h-[88px] so each Apple-HIG-sized 44pt touch target gets
  reliable hit area. Icon size bumped from 6 to 7 for visual weight at
  the larger cell.
