fix: delete activity removes it from index.json; detail page uses lazy load

Browse Source 
delete_activity now updates data_dir/index.json so merge_all no longer
re-adds the summary for a deleted activity, preventing the broken
"Activity not found" state after deletion.

ActivityDetailLoader switches from loadIndex (all year shards) to
loadIndexPaged (first year shard only) + direct file fallback, so
opening an activity detail page no longer downloads the entire history.
