Gate pedigree behind a dog id set in settings

Browse Source 
The pedigree view is now opt-in and tied to your own dog rather than an
always-present free-text search. Add the dog's SKK chip or registration
number in Settings (it rides the synced profile alongside name and
birthday); the 🌳 button stays hidden until one is set, then opens the
page and loads that dog's ancestry directly.

Make repeat opens cheap: memoise the id->hundid resolution server-side so
a cached tree is served without contacting SKK at all, and mirror the
finished tree in localStorage so the page paints instantly and shows the
last-known tree offline.

Adds config.pedigree_id (with an in-place migration for existing DBs).
