Terminology inconsistencies: NAMEs/LAND casing, favorites spelling, 'My Assets' destinations

Same concepts, different words across surfaces:

- Profile tabs say "Names"/"Lands"/"Estates" (`en.json:1684-1686`); the navbar says "NAMEs"/"LAND" (`en.json:709-710`); the marketplace says "Land -> Parcels/Estates".
- The profile maps filter value `parcel` to the label "Lands" (`src/pages/profile/tabs/AssetsTab.tsx:38`) — a category/member confusion.
- "Favourites" (`en.json:1716`) vs "favorites" (`en.json:1720-1721`, `:1166`, `:2077`) within the same tab.
- The label "My Assets" points at two different destinations: `navbarConfig.ts:70` (marketplace/account) vs the profile assets tab.
- Dead key `equipped_wearables` (`en.json:1647`) alongside live `equipped_items`; "Get a Unique Name" vs "Get a name" for the same claim flow.

String-only fix, but key renames must be mirrored across all 6 locale files (these keys exist everywhere).
