synOCR v1.9.99.4 BETA

IMPLEMENTATIONS:

• [GUI] show separate warn icon, if are failed files in history list

IMPROVEMENT:

• [shell] folder monitoring: isolate inotify stderr from events, verify
  "Watches established" before success, extension whitelist
  (pdf / images if img2pdf), skip events while synOCR is busy,
  avoid aggressive stop/restart when the watch list is unchanged,
  and do not run a second OCR pass after monitoring start
  (initial scan covers files already in the input folders)
• [spk] removed unnecessary parameters from conf/privilege (@007revad)

BUGFIX:

• [shell] cap Python interpreter selection at 3.12 (aligned with pin wheels);
  skip newer 3rd-party Pythons (e.g. Immich 3.14 in /usr/local/bin)
