Extract provision_merchant() service for shared use

Both _auto_create_merchant (lazy GET fallback in views_api) and
LNbits' _create_default_merchant (eager signup hook) used to
reimplement merchant + zone + stall creation independently. Moves the
canonical implementation to services.provision_merchant() so both
call sites stay in lockstep — future changes (NIP-17 kind 10050 relay
list, additional default zones, etc.) only happen in one place.

- services.provision_merchant(user_id, wallet_id, public_key,
  private_key, display_name, config): creates merchant if absent,
  default 'Online' zone, default '<username>'s Store' stall, and
  publishes the kind 30017 stall event. Idempotent on the merchant
  pubkey: returns the existing merchant unchanged if one exists.
- views_api._auto_create_merchant: now a 10-line wrapper that loads
  the account, generates fallback keys if missing, then delegates.

The LNbits-side hook (lnbits/core/services/users.py:_create_default_merchant)
will be updated in a companion commit to also call this service.

+Buy and sell products over Nostr using the NIP-15 marketplace protocol.
 
-Buy and sell things over Nostr, using NIP15 https://github.com/nostr-protocol/nips/blob/master/15.md
+Its functions include:
 
-Nostr was partly based on the the previous version of this extension "Diagon Alley", so lends itself very well to buying and sellinng over Nostr.
+- Managing products, sales, and customer communication as a merchant
+- Browsing and ordering products as a customer
+- Tracking order status and delivery
+- Communicating via NIP-17 private direct messages (NIP-44 encryption + NIP-59 gift wrapping)
 
-The Nostr Market extension includes:
-
-- A merchant client to manage products, sales and communication with customers.
-- A customer client to find and order products from merchants, communicate with merchants and track status of ordered products.
-
-All communication happens over NIP-17 private direct messages (NIP-44 encryption + NIP-59 gift wrapping).
+A decentralized commerce solution for merchants and buyers who want to trade goods and services over Nostr with end-to-end encrypted communication.
