fix: resolve Sharp 0.35.1 and BullMQ type incompatibilities after dep bumps

Sharp 0.35.1 moved FormatEnum to a namespace export and removed "avif"
from FormatEnum (now a separate literal in toFormat). BullMQ 5.78.1
bundles ioredis 5.10.1 while we have 5.11.1, causing structural type
mismatch. Also fixes new Biome 1.9 lint rules.
