deps(security): bump pdf-extract → 0.12.0 to pull lopdf 0.42.0

lopdf <0.42.0 has an unbounded-recursion stack overflow on deeply
nested PDF objects (advisory 2026-06-21). The vector through OxiCloud
is the search-index text extractor — anyone who can upload a file can
ship a malicious PDF, and the existing catch_unwind in
text_extractor::extract_pdf does not save us: a stack overflow aborts
the process, it is not a panic.

pdf-extract 0.12.0 requires lopdf ^0.42 which adds the depth bound;
the only consumer call (`extract_text_from_mem`) is API-compatible,
no source changes needed.
