Summary: This is a clean, low-risk localization-only change. It shortens the four auto-transfer title labels from "Configuración de transferencia automática" → "Transferencia automática" and also fixes inconsistent indentation on two unrelated fundExchange* lines. No correctness, security, or regression concerns.

Verified:

• ✅ JSON remains well-formed — trailing commas and structure intact (checked lines around each edit).
• ✅ All three auto-transfer keys updated consistently (bitcoinSettingsAutoTransferTitle, autoswapSettingsTitle, autoswapTitle).
• ✅ No @key metadata (descriptions/placeholders) needed updating — only display strings changed.
• ✅ Indentation fixes (fundExchangeErrorTitleOrdPo404, fundExchangeErrorOrdPo404) align them with the surrounding 2-space style — pure whitespace, no behavior change.

Minor observation (non-blocking): Casing is inconsistent across the keys — autoswapSettingsTitle (line 1462) uses title case "Transferencia Automática" while bitcoinSettingsAutoTransferTitle and autoswapTitle use sentence case "Transferencia automática". This inconsistency pre-existed in the file and was preserved, so it's not introduced by this PR. If you'd like uniform sentence-casing, it could be aligned here, but it's safe to leave as-is.

LGTM. 👍
