chore(quality): rebaseline complexity 2059->2072 + cognitive 890->900 (owner-approved)

The /fix-prs validation-train sweep surfaced a cluster of otherwise-clean
contributor feature PRs (#6973/#7683/#7662/#7672/#7633/#7767) whose per-PR
+1/+2 own-growth collectively exceeded the tip's 3-unit complexity slack
(2056 vs 2059). This was the 4th such block of the day (#7695/#7747/#7768
each needed helper extraction earlier). Owner approved raising both ceilings
to give new-feature PRs breathing room: complexity to 2072 (combined-cluster
2068 + 4 headroom), cognitive to 900 (combined 896 + 4). Structural shrink
stays debt (#3501); tighten via --update next cycle.

+- Rebaseline the cyclomatic-complexity ceiling (2059 → 2072) and cognitive-complexity ceiling (890 → 900) to absorb a cluster of clean contributor feature PRs whose per-PR +1/+2 own-growth collectively exceeded the tip's 3-unit slack. Owner-approved; structural shrink remains tracked in #3501.

PR #7360 (JxnLexn) release-resync: merging origin/release/v3.8.49 to resolve the 3-file conflict (ConnectionRow.tsx/ConnectionsListPanel.tsx/useProviderConnections.ts) unions two already-compliant features in the same already-oversized god-component: release's confirm-delete-account wiring (#7361) and this PR's per-connection quota-visibility wiring. Diffed release-tip-only vs merged violation lists (scripts dumped via getComplexityEslintReport): most entries are the SAME pre-existing violations shifted a few lines (ConnectionRow/getStatusPresentation/inferErrorType — no count change) or marginally bigger (ConnectionRow function complexity 85->86, ConnectionsListPanel function 498->510 lines) from the two ConnectionRow call sites each gaining both PRs' multi-line JSX props. The 2 genuinely NEW crossings are the 'no tag' and 'tagged groups' .map() render callbacks in ConnectionsListPanel.tsx (83 and 85 lines, was <=80 on both parents individually) tipping over 80 lines specifically because both PRs' props land on the same call sites. No new logic was written during the resync itself (only import-statement unions); the growth is inherent to combining the two already-reviewed feature branches. Structural shrink tracked in #3501.
