P2 Badge Preserve folded de-dupe for configured aliases

When a config contains two aliases that differ only by case, this helper now registers both spellings as separate model IDs because the de-dupe key is the exact ID. The execution path still resolves API-key aliases case-insensitively and keeps the first mapping in compileAPIKeyModelAliasForModels (OpenAI-compatible pooling also matches aliases with EqualFold), so a request for the second advertised alias selects this credential but is sent to the first alias's upstream model. Please keep folded de-dupe for configured aliases and apply case-sensitive uniqueness only when adding the extra original upstream ID.

P2 Badge Preserve compat thinking on original IDs

Fresh issue in the static-metadata fix: when an OpenAI-compatible entry aliases a static native model (for example name: "gemini-2.5-pro", alias: "gemini-pro"), this branch copies the native static Thinking field and ignores the OpenAI-compatible thinking value passed in from buildOpenAICompatibilityConfigModels. The alias keeps level-based OpenAI-compatible reasoning, but the newly registered original ID is looked up with Gemini/Claude budget metadata, so direct requests such as gemini-2.5-pro(high) do not have the suffix applied through the OpenAI-compatible executor. Please overlay the provider/config Thinking on top of the static metadata for these original-ID entries.
