[AI Generated] BugFix: bump Pillow and requests for security fixes

[LiliDeng]

Summary

Bump dependency caps to pull in security-fixed releases:

• Pillow: <= 12.0.0 → <= 12.1.1 (fixes GHSA-cfh3-3jmp-rvhc)
• requests: ~= 2.32.4 → ~= 2.33.0 on Python >= 3.10; keep ~= 2.32.4 on Python 3.9 (since requests 2.33+ requires Python >= 3.10) (fixes GHSA-gc5v-m9x4-r6x2)

Validation

Built installers/Dockerfile.linux against this branch in a test workflow and verified package versions:

Package	Required	Installed
Pillow	>= 12.1.1	OK
requests	>= 2.33.0	OK
cryptography	>= 46.0.7	OK (48.0.0, transitive)
PyJWT	>= 2.12.0	OK (2.12.0, from Azure CLI apt package)
azcopy	>= 10.32.4	FAIL (10.32.3, blocked on aka.ms redirect; out of scope)
