fix: standardized cached tokens handling across all providers

Breaking change. Cache tokens moved from usage top-level into ChatPromptTokensDetails (prompt_tokens_details) and ResponsesResponseInputTokens (input_tokens_details), with standardized keys. If you have persisted data (logs, analytics, or custom storage), migrate: (1) move usage.cache_read_input_tokens → usage.prompt_tokens_details.cached_read_tokens or usage.input_tokens_details.cached_read_tokens; (2) move usage.cache_creation_input_tokens → usage.prompt_tokens_details.cached_write_tokens or usage.input_tokens_details.cached_write_tokens.
fix: handle nil properties in tool function parameters
fix: fixed logprobs JSON tag in BifrostResponseChoice (thanks @robechun!)
fix: added proper status check for openrouter keys
