refactor(web): extract common timeline functionality into PhotostreamManager base classes

Create abstract PhotostreamManager and PhotostreamSegment base classes to enable reusable      
timeline-like components. This refactoring extracts common viewport management, scroll         
handling, and segment operations from TimelineManager and MonthGroup into reusable             
abstractions.                                                                                  
                                                                                                  
Changes:                                                                                       
 - Add PhotostreamManager.svelte.ts with viewport and scroll management                         
 - Add PhotostreamSegment.svelte.ts with segment positioning and intersection logic             
 - Refactor TimelineManager to extend PhotostreamManager                                        
 - Refactor MonthGroup to extend PhotostreamSegment                                             
 - Add utility functions for segment identification and date formatting                         
 - Update tests to reflect new inheritance structure
