Content mismatches in profile checks and snapshot comparisons used to
replace the raw expected/actual pair with the decoded per-field table
whenever a decoder could see a difference.
- The raw comparison is always shown first (heading + expected/actual
rows); the decoded per-field table follows when the decoder finds
differing fields.
- The decoded table gets a column-header row carrying the same
expected/actual labels (profile/snapshot names in a comparison) that
the raw rows and the FCI diff table use.
- Matching decoded values keep the 'Decoded values match; raw bytes
differ' note and show no decoded table.
- tests: ef_decode report test extended (raw + decoded + column headers,
custom labels, matching-decoded note); help EN/RU.
