[LWDM] A key error occurs for accounts that are already delegated

[amaslakov]

✅ Checklist

• npx changeset was attached.
• Covered by automatic tests.
• Impact of the changes:
  • Delegated Tezos accounts: header/panel Earn → Stake, not Delegate (fixes delegate.unchanged).
  • Re-delegating to same baker: shows "already delegated" instead of missing-key error.
  • coin-tezos change also hits mobile — [check] mobile locale key.
  • Changeset: ledger-live-desktop + @ledgerhq/coin-tezos patch.
  • "Change baker" moved from header Earn to Row context-menu.

📝 Description

Both Earn entry points (account header, delegation panel) now open the staking flow for delegated accounts instead of a delegation the node rejects as delegate.unchanged. That error now maps to "already delegated to this validator" instead of a missing key.

Pull request overview

This PR fixes the Tezos Earn flow so that already-delegated accounts open the staking flow (rather than triggering a node-rejected delegate.unchanged delegation), and maps that error to the user-friendly InvalidAddressBecauseAlreadyDelegated for both stake and delegate intents. The Earn entry-point logic from the account header and the delegation panel is consolidated into a single pure helper getTezosEarnFlow, with shared cases for empty/no-funds, earning-choice, stake (skipping delegation), and (re)delegate.

Changes:

• Extract Earn routing into getTezosEarnFlow and reuse it from both AccountHeaderManageActions and Delegation/index.tsx, routing delegated accounts to the staking flow with skipDelegation: true.
• In validateIntent, treat delegate.unchanged as InvalidAddressBecauseAlreadyDelegated for both stake and delegate intents (previously only stake).
• Add unit tests for getTezosEarnFlow and the new delegate.unchanged mapping for delegate intent; add a changeset.
