fix: resolve critical/high Dependabot security alerts (#4652)

Upgrade pillow 10.4.0 → 12.1.1 (out-of-bounds write on PSD images),
langchain-core 0.3.76 → 0.3.83 (template injection), and
urllib3 2.6.1 → 2.6.3 (decompression-bomb bypass on redirects).

Bump docling ~=2.63.0 → ~=2.75.0 for pillow 12 compat, and add
uv overrides for pillow/langchain-core to unblock transitive pins
from fastembed and langchain-apify.
