0.8.6

[Polliog]

This pull request updates the project to version 0.8.6 and addresses two key issues: it fixes incorrect handling of epoch dates in ClickHouse queries (which caused traces and metrics data to be unavailable), and improves session validation in the frontend to prevent stale sessions after a volume reset. Additionally, it updates version numbers and documentation throughout the codebase.

Bug Fixes and Improvements

ClickHouse Date Handling:

• All ClickHouse queries for traces and metrics now use the toDateTime64() function to correctly handle epoch dates, instead of passing raw 0 values that ClickHouse cannot parse. This ensures data availability for traces and metrics queries. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15]

Frontend Session Validation:

• The frontend now validates the authentication token against the backend on load (via /auth/me) and logs the user out if the session is invalid, preventing stale sessions after a storage reset.

Version and Documentation Updates

Version Bump:

• Bumped version numbers from 0.8.5 to 0.8.6 across all relevant package.json files, internal logging, and UI displays. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Changelog and Readme:

• Added a new 0.8.6 section to CHANGELOG.md summarizing the above fixes. Updated README.md to reflect the new version, features, and screenshots. [1] [2] [3] [4]
