refactor: move Helm chart to standard directory structure

This commit restructures the paperless-ai Helm chart by moving all files
 from the nested directory (charts/paperless-ai/paperless-ai/) to the
 standard Helm chart directory structure (charts/paperless-ai/). The change
 eliminates the redundant directory nesting that was causing issues with
 Helm chart packaging and installation. No functional changes were made to
 any files - this is purely a directory structure reorganization to follow
 Helm best practices and improve chart maintainability.
