Epic: deliver the approval alert to the phone (relay side of eve#498) #439

Relay side of the cross-repo epic barelyworkingcode/eve#498, which holds the story and the cross-repo contract. Waits for the owner's approval. Depends on barelyworkingcode/eve#495's epic (relay #422) being merged to main.

Story

As the owner, I want relay to deliver the approval alert to my phone, so that it reaches me while the app is closed.

Batches

• Send the approval alert to the phone over APNs, with the key and device tokens sealed in relay #440: the APNs sender, the sealed key and device tokens, the relay push CLI, the ask field on asking, fakerelay's push surface. Credential: the owner approves it.
• Close child (relay): merge the approval-alert epic #441: close child (relay), lines 1 to 4.

Epic branch: epic/439-approval-alert, cut from main after #422 merges.

Contract

Owning contract, merge order and joint close task: barelyworkingcode/eve#498. Each child's ## Contract holds its own file ownership, tests, waits and budget. Child PRs target epic/439-approval-alert.
