fix: simplified remote APIs, timeout settings, replaced tests

[petruki]

This pull request refactors how remote request timeouts are configured and simplifies the remote evaluation logic for switchers. It consolidates multiple timeout settings into a single Timeout field, improves the handling of value checks, and adds comprehensive test coverage for the updated behaviors. Several redundant or error-prone code paths and tests are removed, resulting in a cleaner and more robust implementation.

Remote Timeout Configuration:

• Consolidated ReadTimeout, WriteTimeout, and PoolTimeout into a single Timeout field in RemoteOptions, updating all usages and documentation accordingly.
• Updated the HTTP client construction to use the new Timeout field directly, removing the requestTimeout helper and related logic.

Switcher Value Check Logic:

• Changed CheckValue to always overwrite previous value entries, ensuring only the latest value check is used in remote evaluation.
• Refactored IsOn and IsOnWithDetails to share a common submit method, clarifying the distinction between detailed and non-detailed requests.

Testing Improvements and Coverage:

• Added new tests to verify token reuse, token renewal, correct passing of input parameters, and correct behavior of detailed vs. non-detailed switcher checks.
• Enhanced the remote test server to allow for custom authentication request handling.
• Updated context and client tests to reflect the new timeout configuration and context rebuilding logic.

Codebase Simplification:

• Removed redundant error handling in JSON marshaling and HTTP request creation in favor of simpler code, as errors are not expected in the tested scenarios.
• Deleted obsolete helper functions and their associated tests, such as appendFilteredEntries and requestTimeout.

Documentation Updates:

• Updated the README.md to reflect the new timeout configuration and clarify the meaning of the consolidated Timeout field.

These changes make the remote evaluation logic more predictable and maintainable, while also improving test coverage and documentation.
