fix: report precision — EVC compile-unit scoping, per-contract change labels

[kasperpawlowski]

Regenerated verification reports with the report-precision fixes from euler-xyz/euler-verifier#50 (merged to the engine master). No addresses, commit pins, or verification outcomes change — verify/manifest.json and verify/audits.json are byte-identical; only verify/baselines.json and the rendered reports change.

What changed

Component diffs scoped to deployed compilation units. baselines.json componentPaths now carry :(exclude) pathspecs for source files that are not part of any deployed contract's compilation unit:

• evc: src/utils/EVCUtil.sol (integrator helper, not compiled into the deployed EVC singleton). The 14-chain pin's delta vs the audited baseline is now +4/−1 (was +58/−11): exactly the isSignerValid signer-exclusion hardening. Pin notes and labels updated accordingly; Polygon reads "set-size 10→100 (audited) + signer hardening" at +15/−12 (was +69/−22).
• evk: src/Synths/ (not among the deployed/verified contracts). The 15-chain pin's delta is now +2/−8 (was +15/−8): the twice-reviewed setLTV change plus the one-line ProtocolConfig parameter default.
• reward-streams: src/StakingRewardStreams.sol (only TrackingRewardStreams is deployed in scope; no diff impact).

Per-contract "What changed" precision. Each table row now reflects only the changed files inside that contract's own compilation unit: rows whose unit contains none of the component's changed files read ≡ baseline (unit), and rows covering a subset show recomputed +/− counts (e.g. the ProtocolConfig parameter change no longer appears on the sequenceRegistry/eVaultFactory rows; EulerSwap per-contract counts are now per compilation unit).

Flagged assessment placement. Flagged assessment notes render directly above the product-section table their contract belongs to instead of the top attention block, which now carries only unproven/waived entries.

Every difference vs the previously published reports is one of the changes above (plus the generator reference now reading master).
