feat: install LOAD failures get the compatibility-test analysis (v3.6.53)

ramShowInstallResult appends ramCompatDetailHtml(data, capMem) to the
install modal (the modal content is HTML now - the step lines are escaped
and ramOpModalFinish takes the asHtml mode), so a failed LOAD / INSTALL
[for load] shows the same block analysis as the compatibility test:

- the failing block's CAP section (load-file byte range and components, and
  what completes there), with the JC VM spec 4.5.2 note - or 'the import
  list already passed' when the failure is later in the file;
- the remote status word with its name;
- the import list at the CAP's own versions (a real install runs no probe);
  the closing hint points at the compatibility test ('Set all 0.0' first,
  then bisect), while a probe run keeps the lower-the-versions wording.

ramInstallFailHint stays as the short inline hint; INSTALL [for install] and
/api/ram-install-app failures show no block (the LOAD guard in the helper).
