🐛 fix(tokens): correct main Chat button navigation to prevent 404

The primary "Chat" button on the tokens table navigated to a 404 page
because it passed incorrect arguments to onOpenLink (using a raw
localStorage value instead of the parsed chat value).

Changes:
- Build chatsArray with an explicit `value` for each item.
- Use the first item's `name` and `value` for the main button, matching
  the dropdown behavior.
- Preserve existing error handling when no chats are configured.

Impact:
- Main "Chat" button now opens the correct link, consistent with the
  dropdown action.
- No API/schema changes, no UI changes.

File:
- web/src/components/table/tokens/TokensColumnDefs.js

Verification:
- Manually verified primary button and dropdown both navigate correctly.
- Linter passes with no issues.
