The previous /heaps/{id}/convert dropped photos directly into a chosen
source root, which is rarely what you want — Lightroom-style behaviour
is "make a folder named after the collection inside the library".
Now the dialog lets you do that.
Backend
- HeapConvertBody gains an optional subfolder_name field. Path
separators and dot-segments are rejected. When set, the handler
joins it onto the resolved parent_dir, mkdir's it if missing, and
uses the resulting path as the move/copy destination. Otherwise
the parent_dir itself is used (unchanged behaviour).
- The Folder DB row for the destination is created via the existing
scanner get_or_create_folder helper so dedupe + path normalization
stay consistent across the codebase.
- The target source root id is propagated through both the source-
root and folder branches so the new Folder row is correctly
parented when subfolder_name is set on a folder target too.
Frontend
- HeapConvertDialog grows a "Subfolder name" input that prefills
with the heap name when the dialog opens. Trimmed empty value
drops directly into the parent. A live hint below the input
shows exactly which path will be created (or that the parent
will be used).
- api.ts heaps.convert() signature accepts an optional
subfolder_name field; the dialog sends it via mutationFn.
