ui: header preset indicators — ADM key glyph, SCP80/SCP81 completeness (v2.6.1)

- the ADM badge gains a trailing key glyph (ADM ✓ ⚿ / ADM ✗ ⚿) when the
  preset matching the equipped card's ICCID carries an ADM key; the four
  tooltip states cover key/no-key x verified/not-verified
- new gray SCP80/SCP81 markers after ADM, shown only when that preset has
  all SCP80 fields (KIc/KID, SPI1/SPI2, counter, KIc/KID keys) or the SCP81
  PSK pair filled in; hidden without a card session, a matching preset or
  the fields, never color-coded
- cardsScp80Complete/cardsScp81Complete/cardsAdmPresent/cardsMatchedPreset
  helpers; cardsRender reuses the SCP81 predicate
- tests: ADM four-state badge, marker show/hide, predicate whitespace
  handling, header markup order; help EN/RU updated; SW cache simple-v201
