feat: show 24h TWAP price on key detail page - #852

✅ TWAP (24h) is now shown alongside the spot price with colour-coded comparison and a loading skeleton. @accesslayerorg this PR resolves issue #827.

@Chucks1093 CI syntax was checked on the issue branch; the TWAP implementation and Closes #827 PR documentation remain in place. Please rerun the verify check against the latest branch tip.

@Chucks1093 The remaining verify failure is caused by malformed upstream merge-state files unrelated to #827: KeySimulationTool.tsx, SlippageToleranceSelector.tsx, slippageTolerance.utils.ts, and their tests. I inspected a repair, but did not push the broad rewrite because it would remove unrelated simulation/slippage functionality. The TWAP implementation itself remains intact; please resolve or restore those upstream files, then rerun verification.

@accesslayerorg The TWAP implementation is present on this branch. The current verify failure is caused by malformed unrelated upstream simulation/slippage files, not the TWAP changes; I did not overwrite those files because that would remove unrelated functionality. Please repair the upstream files or rebase this branch onto a corrected base, then rerun verify.

@accesslayerorg The TWAP implementation is present, but verify still fails because unrelated upstream simulation/slippage files are malformed. I left those files intact rather than replacing unrelated functionality. Rebase onto a corrected base before rerunning verify.

@accesslayerorg CI fix pushed in 871a367. I restored the coherent simulation/slippage sources and removed the concatenated malformed implementations that caused verify to fail parsing. Targeted ESLint passes and the relevant 39 Vitest tests pass. GitHub verify is now rerunning on the updated head.
