feat: clean up the Explore UX (v3.6.45)

- Explore runs inline: no blocking modal (that stays for the install
  operations, which can leave a half-loaded package; Explore leaves the
  card consistent).  A test guards that ramExplore never calls the modal.
- Minimal success line: just OK - the details live in the explorer below;
  error runs keep the detailed 'Partial - ...' line.
- Counts moved into the section headings (Applications / Applet Instances
  (n), Executable Load Files (ELFs) / Packages (n)); the redundant '1 ISD'
  count is gone (P1=80 returns the ISD as a single occurrence, GP
  11.4.2.1).
- The RAM command format line gained a tooltip: compact = TS 102 226
  5.2.1 command string, expanded = the AA/22 scripting template (5.2.1.0),
  detected per operation with a read-only GET STATUS probe.
- The expanded-registry checkbox is relabelled 'Fetch expanded registry
  details (load-file / SD associations)' with a tooltip (extra secured
  packets, card support varies, the fallback is automatic) and is now a
  sticky per-browser preference (simple_ram_expanded).
