refactor(types): replace implicit and explicit Any across 11 modules 
Types the values that were flowing through as Any in the highest-density
modules, using shapes the code already assumes: TypedDicts for the JSON
payloads read by literal key, Protocols for the prisma rows, existing
litellm types where they were already modeled, and `object` where a value
is only stored and forwarded.

Annotation-level only, no runtime behavior change. New annotations use
read-only views (Mapping / Sequence / tuple) rather than dict / list, so
LIT001 drops alongside the Any counts instead of trading one budget for
another. No suppressions, casts, or type guards were added.

basedpyright across the touched files: 1547 -> 856 errors, with reportAny
down 399 and reportExplicitAny down 134, and no rule increasing.

Caching on LiteLLM

LiteLLM supports multiple caching mechanisms. This allows users to choose the most suitable caching solution for their use case.

The following caching mechanisms are supported:

  1. RedisCache
  2. RedisSemanticCache
  3. QdrantSemanticCache
  4. InMemoryCache
  5. DiskCache
  6. S3Cache
  7. AzureBlobCache
  8. DualCache (updates both Redis and an in-memory cache simultaneously)
