Refactor Fork Auction Truth Flow into Dedicated Modules

[KillariDev]

Summary

• Split fork truth-auction flow into dedicated modules by introducing new UI components, hooks, and lib abstractions for bids, settlement state, book data, and pagination.
• Replaced legacy reporting/truth-auction reporting plumbing with a new transaction/action model and updated operation hooks, tray actions, and marketplace views.
• Simplified and de-duplicated contract interaction surface by moving auction/fork-specific wiring in ui/ts/contracts and adjusting related deployment/integration hooks.
• Removed outdated operator/reference docs and simplified auction documentation in docs/auction-design.md and docs/whitepaper_placeholder.html.
• Updated tests to cover the new truth-auction modules and removed obsolete test coverage tied to deleted modules.

Manual review: no blocking findings found.

I focused on the UI truth-auction refactor:

• The extracted bid disposition, book, tick/price, and settlement helpers match the prior component logic in the paths I compared.
• The settlement reducer preserves mixed claim/refund settlement, ignores stale transaction results, and covers the new refund-only route through refundLosingBids with tests.
• The split bid, market, summary, and imported-settlement components preserve the old loading, empty, and action-control states I checked.
• git diff --check origin/main...origin/pr/370 is clean.

Caveat: GitHub Required CI was still pending at review time, so wait for that gate before merging. I did not run the full local QA suite during this manual review.
