feat(inspect): port legacy parser rules the new resolver missed (A1111)

R3: an accumulating batch saver repeats the A1111 parameters record once
per batch item, identical except "Batch index: N". The bounded PNG reader
now keeps the last copy (Pillow's rule, which #165 relied on) instead of
calling the file unreadable. Any other difference, including a missing or
second batch index, is still a conflict, and decoding the copies draws from
the duplicate role budget.

R4: parameters text that starts with "Negative prompt:" has an empty
positive (#165), instead of showing the delimiter line as the positive.

R5: the settings footer may be followed by sd-dynamic-prompts' one-line
"Template:" and "Negative Template:" records, and may be "Steps: N" alone
when there is no full footer.

R10: commas inside A1111's quoted settings values no longer split them, so
an "ADetailer prompt" with a comma keeps the other facts known.

The facts' A1111 reader mirrors R4, R5 and R10; the default (ingestion)
profile keeps the historical split. Also from the Task 2.7 review: a guard
test fails on any uncoded unresolved reason without a user line (M1), and
the encoder bounds role lines to the client's 512 code units (M4).
