v3.25.8: the custom (per-data-object) FCI check in profiles

fciMode 'custom' + fciDos + fciExtra ('ignore' default / 'fail'): each
row is a data-object key (the decoder's keys - 2/4-hex tags and the
nested A5/xx/C6/xx children), a mode (value / present / absent) and, for
value, hex with the contents vocabulary (no '?' = prefix - 8B + 2F06 =
any EF.ARR record of that FID, the record-number-agnostic form; ? =
fixed-length nibble mask).  Only the listed objects are checked; 'fail'
also rejects any unlisted object (order-insensitive strictness).

The scan dialog's FCP/FCI selector gained the mode ("Custom (per data
object)" - the acronym spelled out) and seeds every rule created from a
card or a snapshot with that file's captured FCI objects; a manually
added rule starts empty, and the editor offers "load from the captured
FCI" when the list is empty and the rule carries an FCI.  The report
reuses the access-rules diff marks; the aspect is 'FCI (custom)',
separate from 'Exact FCI' (the filetype/size/record checks still run).

Docs: help EN/RU (the check bullet + the scan dialog paragraph).
Tests: the check (exact/prefix/mask, present/absent, duplicates, nested
keys, extras ignore/fail, the empty list, the parse error, the
size/record checks still running), the seeding, the editor
rows/datalist/load link, the report, the aspects, the validation.
