Bump graphiti-core version to 0.28.2 (#1315)

* Bump graphiti-core version to 0.28.2

Update version across pyproject.toml, MCP server, server, Docker configs, and root lock file.
MCP server and server lock files will need regeneration after PyPI publish.

* Revert MCP server version bump until release

MCP server depends on graphiti-core from PyPI, so the version bump
should happen after the 0.28.2 release is published.
