🖍️ fix: Honor Agent Image Detail Settings (#15407)
* 🖼️ fix: Apply an Agent's Configured Image Detail

The Agent Builder exposes an Image Detail slider and saves it to
`model_parameters.imageDetail`, but nothing ever read it back: `encodeAndFormat`
resolves the level from `req.body.imageDetail`, which the agents route never
populates, so every image was encoded as `detail: "auto"`. Providers that reject
`auto` — MiniMax's OpenAI-compatible API among them — fail every image upload
through an agent, and the setting that would fix it has no effect.

The root cause is a classification error rather than a missing argument.
`extractLibreChatParams` splits LibreChat's own settings out of an agent's model
parameters, and its key set is derived from the `librechat` group in
`parameterSettings`. `imageDetail` sat in `baseDefinitions` instead, so it was
neither extracted for LibreChat's use nor stripped from the options handed to the
provider.

It is now grouped with `resendFiles` and the other LibreChat-level parameters,
which gives it the same path those already take: extracted during agent
initialization, carried on the initialized agent, passed to the client, and read
by `encodeAndFormat`. `AgentClient.getSaveOptions` already expected
`options.imageDetail` — nothing had ever populated it.

The request body still wins where it is set, so the classic endpoints keep
resolving detail from conversation settings exactly as before.

Fixes #15359

* 🔤 fix: Type Image Detail as Its Enum, Not a Bare String

`TConversation.imageDetail` is the `ImageDetail` enum, so the extractor's return
type and the initialized agent's field are now declared as that enum rather than
widened to `string`, and the tests pass enum members instead of raw literals.

Caught by CI's type check, which I had run before adding the tests and not after —
jest compiles the specs through babel, so the suite stayed green over a type error.
