v1.45.2

Added

• Subscription categories and payment methods can now be renamed, recolored (categories only), and removed from the "Manage categories and payment methods" dialog in Budget → Subscriptions, in addition to being added and reordered. Removing one detaches any subscriptions still using it (they fall back to uncategorized or unspecified) and the confirmation shows how many are affected; removing a category also cleans up its mirrored Budget subcategory and detaches the linked expense entries (#551).
