fix(nip56): address post-merge review findings on report ingestion

[Priyanshubhartistm]

Description

Following up on #770 after a collaborator review on the merged PR turned up four real bugs in report ingestion: dead rows for targetless reports, silent truncation of multi-target reports, non-atomic inserts across a report's rows, and the first report after a restart blocking on a cold WoT graph rebuild. Fixed all four.

Related Issue

Closes #785

Motivation and Context

All four bugs were already live on main

Confidence Score: 2/5

The PR is not yet safe to merge because hot-enabling WoT can leave its graph empty, the first event can still block on a cold build, and accepted reports can lose targets.

Findings

1.  Hot-enabled WoT stays empty ▶
2.  First event still waits ▶
3.  Accepted reports lose targets ▶

Summary

This PR skips targetless report rows, persists multi-target reports in one transaction, expands target extraction, and starts WoT graph building when its singleton is created.

• The new warm-up needs to account for hot-enabling WoT and does not run early enough to avoid the first event’s cold-build delay.
• The new target cap accepts reports while discarding targets beyond twenty.
