Group Settings panes into clearer subsections

[FuJacob]

Summary

Tightens the Settings layout so every grouped card has a meaningful header and related controls live together.

• General: the top toggles (Enable Globally, Fast Mode) now sit under a Status header, and the trailing Open Welcome Guide row gets a Help header instead of floating below Appearance.
• Writing: the top section is renamed Length (the pane itself is already titled Writing), and the Profile mega-card is split into three cards: Profile (caption + Name), Languages, and Rules. Each editor renders its own internal label and Clear control.
• Apps: the section header is renamed Disabled Apps so it doesn't duplicate the tab title.
• Shortcuts: split into Mode (acceptance mode picker) and Keys (Accept Word, Accept Entire Suggestion).

Copy-only / layout-only change. No behavior, persistence, or binding changes.

Validation

Local SwiftLint pass (swiftlint lint --quiet on the four modified files): exit 0. Did not run xcodebuild this round; changes are pure SwiftUI section rearrangement.

Risk / rollout notes

Low risk; affects only the redesigned Settings panes under Cotabby/UI/Settings/Panes/.

Greptile Summary

This is a pure SwiftUI layout reorganisation across the four Settings panes and the two shared editor components (LanguageTagsEditor, CustomRulesEditor). No bindings, persistence, or business logic are touched.

• General / Shortcuts / Apps: previously anonymous or redundantly-named Section headers are given explicit labels ("Status", "Help", "Mode", "Keys", "Disabled Apps"); the Shortcuts pane is split from one section into two.
• Writing: the "Profile" mega-card is broken into three separate Sections (Profile, Languages, Rules); a new showsTitleHeader: Bool = true parameter on both editor components lets the Section header carry the label while preserving the Clear button, with the default true keeping existing callers (SettingsView, WelcomeProfileStepView) unchanged.

Confidence Score: 5/5

Safe to merge — all changes are SwiftUI Section header renames and card splits with no logic, binding, or persistence modifications.

Every file touched is a pure layout reorganisation: string literals for Section headers are renamed or added, one pane is split into two sections, and two shared editor components gain an opt-in showsTitleHeader parameter that defaults to true, leaving all existing call sites (SettingsView, WelcomeProfileStepView) behaviorally identical. There are no data model, persistence, or control-flow changes anywhere in the diff.

No files require special attention.

Important Files Changed

Filename	Overview
Cotabby/UI/Settings/Panes/WritingPaneView.swift	Splits the old 'Profile' mega-card into Profile (name only), Languages, and Rules sections; renames 'Writing' → 'Length'; passes showsTitleHeader: false to the two editors so Section headers carry the title.
Cotabby/UI/CustomRulesEditor.swift	Adds showsTitleHeader: Bool = true param; wraps the header HStack in `if showsTitleHeader
Cotabby/UI/LanguageTagsEditor.swift	Mirrors the showsTitleHeader addition from CustomRulesEditor. Existing callers in SettingsView and WelcomeProfileStepView omit the param and keep the default true, so they are unaffected.
Cotabby/UI/Settings/Panes/GeneralPaneView.swift	Adds explicit 'Status' and 'Help' headers to the two previously anonymous Sections; no control or binding changes.
Cotabby/UI/Settings/Panes/ShortcutsPaneView.swift	Splits the single 'Shortcuts' Section into 'Mode' (AcceptanceModePickerView) and 'Keys' (keybind rows); no logic changes.
Cotabby/UI/Settings/Panes/AppsPaneView.swift	One-line rename: 'Apps' → 'Disabled Apps' to avoid duplicating the tab title. No other changes.
