fix(market): resolve stall_id from a-tag when content omits it

Browse source 
NIP-15 lists stall_id inside the JSON content of kind-30018 product
events, but some publishers (older nostrmarket builds, third-party
clients) omit the field and only emit the parent reference via the
a-tag of the form ["a", "30017:<merchantPubkey>:<stallId>"].

Adds resolveStallId(event, productData) which:
  1. Reads productData.stall_id when present (the spec-canonical path)
  2. Falls back to the a-tag prefixed "30017:" when content omits it
  3. Returns 'unknown' as a sentinel that won't match any real stall

Both code paths in useMarket.ts (loadProducts batch and
handleProductEvent live-update) now use it. Combined with the
addStall sweep from eb3393f, products eventually link to their
parent stall regardless of order or which form the publisher used.

This DOES NOT fix orphan products whose referenced stall genuinely
isn't on the relay — those still render "Unknown Stall" because no
stall exists to link to. Investigating that separately.
