feat(ui): route locked tiers through About

Keep non-owner resolution choices visible but muted. Selecting one preserves the free tier and opens About; external navigation is only the explicit llamacasty.com link. Ref: https://streamlabs.com/desktop

 | `BackgroundEffect.cs` | **TASK 51:** per-webcam background effect enum `None` / `Remove` / `Blur`, carried by `WebcamSceneConfig` |
 | `BorderColorPalette.cs` | **TASK 60:** the colours the webcam's border-colour drop-down offers — `NamedColor(Hex, Name)` + `BorderColorPalette.All` (the single source of truth; the drop-down is bound to it) and `NameOf(hex)` (case-insensitive; **empty** for a colour outside the palette — "no name" is the honest answer, TASK 62). The creator asked for a colour NAME next to each hex: `#e94560  Crimson`. **TASK 63:** `EntryFor(hex)` (the palette entry for a hex, case-insensitively; a nameless entry for a colour outside the palette) and `OptionsFor(hex)` (the palette + that entry) — the two the drop-down binds to; `NamedColor.ToString()` is `"Crimson (#e94560)"` |
 | `WebcamSceneConfig.cs` | Per-scene webcam placement (subclass of `SceneElement`): geometry + `IsVisible` + border (`BorderColor`/`BorderOpacity`/`BorderWidth`/`BorderAnimation`) + `VideoImageSource`; `WebcamId` links to `Webcam`; **TASK 51:** `BackgroundEffect` + `BackgroundStrength` (0..1, default 0.5) + the radio-pill surface `RemoveBackground`/`BlurBackground` (one on turns the other off; both off = None) + `HasBackgroundEffect` (shows the strength slider); **TASK 57 (the "vv" feature):** the vertical (9:16) tier's OWN placement per scene — `VerticalX/Y/Width/Height/VerticalClipShape/VerticalRectWidth/VerticalRectHeight` (persisted, NULL = no vertical placement yet) + the transient `VerticalBand`/`VerticalLayoutLive`/`LandscapeX…LandscapeRectHeight` (the parked 16:9 layout) + `BeginVerticalLayout`/`EndVerticalLayout`/`CommitLiveLayoutToVertical` (the tier swap) and the `X`/`Y`/`Width`/`Height` overrides that clamp every write into the band; `VerticalShapeLocked` (the Chat scene's vertical layout is rect-only) **overrides** `ClipShape` + `ToggleClipShape()` so no writer can slip a circle in |
