fix(schema): close LiteLLM_MemoryTable model brace dropped during merge

The rebase against `litellm_internal_staging` (which added
`LiteLLM_AdaptiveRouterState` / `LiteLLM_AdaptiveRouterSession`) left
the closing brace of `LiteLLM_MemoryTable` missing in all three
schema copies — the next model declaration ended up parsed as a field
of the memory table, surfacing as the CI prisma error:

    error: This line is not a valid field or attribute definition.
      -->  schema.prisma:1250
       |
    1249 | // Per-(router, request_type, model) Beta posterior for the adaptive router.
    1250 | model LiteLLM_AdaptiveRouterState {

Add the missing `}` (and the standard blank line) after the memory
table's `@@index([team_id])` in `schema.prisma`,
`litellm/proxy/schema.prisma`, and
`litellm-proxy-extras/litellm_proxy_extras/schema.prisma`.

`prisma generate --schema litellm/proxy/schema.prisma` now runs clean;
27/27 memory unit tests pass.
