Start and end time can be set in program config but only applies in direct play

got seek and end time working on non-direct play

Enhance program duration calculation and entry creation in channel services and guide

improved guide generation

Add debug logging and really agressive program merging logic and placeholder avoidence in XMLTV writer

Add a final pass duplicate detection and merging logic in _smartMerge function

Refactor XMLTV writing logic: enhance debug logging, streamline program merging, and improve error handling

backwards compatibly

Human readable time

Refactor program configuration modal: move optional position offsets to collapsible advanced options section

Update program configuration modal: rename position offset labels to custom start and end time

Changed how I build the guide based on an implementation that's closer to the original implementation and requires less changes.

Reverted Unneeded Changes

Simplified how StreamSeeK and custom end positions are applied in both transcoding and direct play.

Implement merging of adjacent programs with the same ratingKey in TVGuideService

Made merging-adjacent programs optional and disabled by default

custom time can actuall be set

cleanup

Enhance time input validation for program duration and seek positions
