feat(web): the console joins the shared design system

web/ was the last app on its own palette — a neutral #0f1117 ground with an
indigo accent, unrelated to the logo navy that site/ and adminsite/ are built
on. It now draws from the same tokens, so all three apps are one system.

It stays locked to dark, taking site/'s dark values. That is what keeps
adminsite/'s light default meaningful: an operator with both open tells them
apart by the ground before clicking anything destructive, and now that both
are the same palette, the ground is the only thing left doing that work.

The colour names stay this app's own — text-primary, border, surface rather
than ink, rule, panel — because every screen already reads that way, and
adminsite/ already establishes that each app names the shared tokens after
its own subject.

Tokens are stored as RGB channels with the hex in a trailing comment. The
console leans on Tailwind opacity modifiers far more than the other two
(bg-danger/10, border-accent/50, ring-accent/30), and <alpha-value> only
compiles against channels; the comments keep the three token blocks
diffable by eye.

Beyond colour:
- radii collapse to site/'s 4px in tailwind.config.ts rather than rewriting
  ~140 rounded-lg classes; rounded-full is untouched for dots and pills
- badges become site/'s chip — mono, uppercase, tracked, currentColor rule,
  no fill — keeping their dot so state is never colour alone
- table column heads take the keyed-label idiom, at text-secondary rather
  than tertiary, which lands under 4.5:1 at that size
- sidebar marks the active item with an accent bar, the device site/ uses
  for the chosen plan, instead of a filled pill that reads as pressable
- filled accent and danger buttons take accent-ink; the dark accent is a
  light blue and danger a coral, and white on either was unreadable
- login's packet pulses shift from green to the accent, so the sign-in
  screen is the same two blues as the marketing hero

The last hex literals and stock-palette classes are gone; the only ones left
are NetworkBackground's canvas fills, which cannot read a CSS variable and
are commented with the token each came from.

Only the web image rebuilds from this.
