Migrate to applesauce v6

Remove applesauce-factory (deleted in v6) and bump applesauce-core,
applesauce-relay, and applesauce-signers to ^6.2.x. Rewrite all
EventFactory usage from the removed constructor API
(`new EventFactory({ signer }).sign(template)`) to the new chainable
builder (`EventFactory.fromKind(k).content(...).sign(signer)`).

Remove `relay.eoseTimeout` overrides in nostr-auth — the eoseTimeout
property was removed in v6; NostrConnectSigner now uses persistent
subscriptions that don't rely on EOSE-based timeouts.

Update photo-gallery test mock to use 64-char hex pubkeys/ids/sigs
because v6's sign() validates event structure via validateEvent().

Also includes safe semver bumps to all other dependencies.
