ci: tolerate ANSI reset escapes in security verdicts; fix tier product counts (#7712)

The overnight run after #7708 proved the security verdict greps still
counted zero: real verdict lines are '\e[1;31m[FAIL]\e[0m STS-105 ...'
— the reset escape sits between the tag and the case id, and the
pattern only tolerated escapes before the tag. Allow escapes on both
sides; the fixture now emits the reset too, mirroring the real suite.

The tier case table is produced by rustfs_tier_report.py and its rows
lead with the topology column, so the case-ID-first table grep matched
nothing ('Product result: 0 passed, 0 failed'). Parse the PASS/FAIL
counts from the '## Case Summary' bullets the report always emits,
falling back to a topology-aware table grep.
