Standardize timeout values to floats in seconds

[maxisbey]

Summary

Standardize all timeout parameters across the SDK to use floats representing seconds, following Python ecosystem conventions.

Problem

Timeout values in the SDK may use inconsistent units or types across different modules. The Python ecosystem (stdlib, httpx, starlette) consistently uses floats representing seconds for timeouts.

Goal

• All timeout parameters should be float type representing seconds
• Follow the principle: "be lax in what you receive and strict in what you return"
• Align with conventions from httpx, starlette, and Python standard library
