Context

The wallet always generates a 24-word Secret Recovery Phrase. We want to:

• Show an index with a dot before each word (e.g., 1.hat, 2.word, …).
• Render the 24-word phrase in a 4-column × 6-row grid.

Scope

• UI only: prepend {index}. to each displayed word.
• Layout: force 4 columns × 6 rows for the 24-word phrase.
• Preserve copy behavior: clicking copy must copy the real 24-word phrase (no indices).

Requirements

• Each cell shows i + 1 + . before the word (e.g., 1.hat).
• Use a 4×6 grid for 24 words.
• Copy feature copies mnemonicWords.join(" ") (no indices).
• Input mode remains editable; adornment shows the index.

Files likely impacted

• packages/app-extension/src/components/common/Account/MnemonicInput.tsx
  (components: MnemonicInputFields, _ReadonlyMnemonicTable)
