Port expanded About support copy to redesigned AboutPaneView

[FuJacob]

Summary

#411 expanded the support copy in About from one paragraph to two, but it edited Cotabby/UI/SettingsView.swift, which is the legacy settings root. The pane the redesigned Settings window actually shows is Cotabby/UI/Settings/Panes/AboutPaneView.swift (see its own file header: "Consolidates what used to live across three legacy sections..."). The redesign is gated by isRedesignEnabled in SettingsCoordinator and is on for users, so #411's copy never reached the UI.

This ports the same two-paragraph mission + ask into AboutPaneView.supportRow.

Validation

xcodebuild -project Cotabby.xcodeproj -scheme Cotabby -destination 'platform=macOS' build
# ** BUILD SUCCEEDED **

swiftlint lint --quiet
# 0 issues

Visual check deferred to a screenshot on the running app; the diff is a 1-to-1 copy port from the legacy view's expanded label into a VStack(alignment: .leading, spacing: 8) inside the existing LabeledContent label, matching how the legacy view did it.

Risk / rollout notes

• Copy-only change inside one @ViewBuilder. No control flow, no state, no new dependencies.
• Legacy SettingsView.swift is left untouched. It is still wired behind isRedesignEnabled in SettingsCoordinator, so deleting it is a separate decision.

Greptile Summary

This PR ports the expanded two-paragraph support copy (introduced in #411) from the legacy SettingsView.swift into the redesigned AboutPaneView.swift, which is the pane that actually renders for users when isRedesignEnabled is true.

• Replaces the original single-paragraph label in supportRow with a VStack(alignment: .leading, spacing: 8) containing two Text views, matching the structure added to SettingsView.swift in Expand About support copy to two excerpts #411 character-for-character.
• No logic, state, or dependency changes — copy-only edit inside a single @ViewBuilder property.

Confidence Score: 5/5

Safe to merge — copy-only change with no logic, state, or dependency impact.

The change is a character-for-character port of two Text strings and their VStack container from the legacy SettingsView.swift into AboutPaneView.swift. There is nothing to break: no control flow, no state mutations, no new imports, and the modifier chain is identical to the source. The legacy view is left untouched, so neither code path regresses.

No files require special attention.

Important Files Changed

Filename	Overview
Cotabby/UI/Settings/Panes/AboutPaneView.swift	Single-paragraph label in supportRow replaced with a two-paragraph VStack; copy and modifiers are a 1-to-1 match of the legacy view. No logic changes.
