fix: replace bare except with except Exception (4 modules)

[TrueFurina]

Summary

Four bare except: clauses catch everything, including
KeyboardInterrupt/SystemExit, and hide programming errors as if they were
expected failures:

• src/modules/export/pdf.py (PDF drawing loop) — skip on draw error
• src/modules/utils/file_operations.py — return False when a file cannot be
  read
• src/modules/utils/http_client.py — fall back to binary decode when
  response.text() fails
• src/modules/utils/parse.py (2 places: JSON-path access + regex match) —
  return False on miss

Replace all with except Exception: — intended behavior unchanged, but
unexpected exceptions now propagate.

Verification

• python -m py_compile <the 4 files> → OK
• grep -rn "except:" src/ → 0 remaining bare handlers

Files changed

• src/modules/export/pdf.py
• src/modules/utils/file_operations.py
• src/modules/utils/http_client.py
• src/modules/utils/parse.py (2 lines)

Hi maintainers — just checking in on this PR. It fixes bare except: clauses (KeyboardInterrupt/SystemExit were being intercepted first). Happy to adjust anything to help get this merged. Thanks!
