Transmog Hunter Forever

## v2.1 — UI Makeover

TMHF traded its obsidian and violet look for the game's own windows, so it now looks like it shipped with WoW Forever (and matches CGForever and Murloc Census Bureau if you run those).

### Changed
- **Main window** — Now built on the game's portrait frame: the real title bar, the red X, and the TMH icon in the round corner. The player or list name shows in the title bar, with status and set completion right under it.
- **Slot list** — Sits in a recessed inset, like the game's own list windows.
- **Tabs** — Inspect, Wishlist, Saved Looks, Tracked Looks, and History are now the game's own bottom tabs, hanging off the bottom edge like the character pane.
- **Buttons** — Every button is the standard game button, including the per-row Delete buttons.
- **List rows** — The violet tint is gone. Rows are a neutral dark with a gold hover and selection.
- **Export, Help, and list windows** — Same portrait frame and inset, so every TMHF window matches.
- **Version line** — Moved to the top right of the main window to make room for the tabs.

### Under the Hood
- Every game template is created safely. If a client is ever missing one, that piece falls back to the old flat look instead of throwing an error.
- Nothing about how TMHF works has changed: rows, colors for Collected/Missing, `[W]`/`[T]` tags, and ESC behavior are all the same.
