fix(layout): cap RichChatView/ProjectSessions idealHeight; revert broken detail wrap

Prior commits tried to solve the "window grows whenever Chat or
Sessions is selected" bug by wrapping NavigationSplitView's detail
slot with an explicit frame (`205bb2c`). That broke the HSplitView
layout in Projects — the project list column, dashboard header,
tab bar, and Sessions-tab header all vanished. Scarf's convention
(PlatformsView.swift:12 calls it out explicitly) is to apply
size constraints on individual HSplitView columns, never on an
outer wrapper.

This commit:

- Reverts the broken ContentView.swift outer frame from `205bb2c`.
  NavigationSplitView.detail goes back to its v2.2.1 shape.

- Caps the subtrees whose natural ideal heights are what was
  actually pushing the window past the screen:
  - RichChatView: `.frame(minHeight: 0, idealHeight: 500, maxHeight: .infinity)`
    on the outer VStack. The message list uses a plain VStack
    (deliberately, to dodge the LazyVStack whitespace bug — see
    RichChatMessageList.swift:13-24), so its natural ideal grows
    with every message. Capping idealHeight at 500 gives the
    window a screen-safe starting size without limiting how tall
    the view can flex when the user drags the window bigger.
  - ProjectSessionsView: same treatment with `idealHeight: 400`.
    Replaces the earlier `.frame(maxWidth: .infinity, maxHeight:
    .infinity)` which set MAX but didn't influence what got
    reported upward as ideal.

- Xcode regenerated Localizable.xcstrings during builds; riding
  along.

`.frame(idealHeight:)` is the specific SwiftUI knob that overrides
a child's reported ideal on the way up — `maxHeight: .infinity`
alone doesn't. With `.windowResizability(.contentMinSize)` (still
in scarfApp, left alone), the window sizes itself to the reported
ideal on open and respects user drags above the content min. With
a screen-safe ideal, the window opens at a usable size and never
pushes past the desktop.

User-verified: window behaves correctly across section switches,
resize persists, chat input bar always visible.
