Add counter for free tier model usage

[alexxtaurus83]

It will be useful if user using free tier models can set limits for those models manualy.
RPM: Requests per minute
RPD: Requests per day
TPM: Tokens per minute
TPD: Tokens per day
Like:
https://console.groq.com/docs/rate-limits
https://ai.google.dev/gemini-api/docs/rate-limits#free-tier
User should be able to set limits for each model. As app already counting token usage. It will be great to show user how much was used according to the details he set at model configuration. So, he can see how many tokens and request available for free tier.

I see at the top of the chat progress bar with context window, so might be needed to add 4 additional bars at the top. Might be with hide\show feature.
