Subject: [PATCH] feat(pathanalyzer): message text filter

Free-text case-insensitive substring filter on message content, next to
the other toolbar filters; combines with them and is reset by Clear.

Verified live via Playwright: content match returns only matching rows
(5/606), combines with the sender filter, Clear restores the full set.
