Add Account Name Editing Functionality in Settings

Implement Account Name Edit Feature to Avoid Deletion and Re-Addition Process.

Users need the ability to edit or rename their connected accounts directly through the settings interface instead of having to delete and re-add accounts when they want to change the display name. This feature would include an "Edit Name" or "Rename Account" option within the account management settings, allowing users to modify account labels or nicknames while preserving all historical data, trade records, and performance metrics associated with that account. The functionality should include input validation for duplicate names, confirmation dialogs to prevent accidental changes, and immediate reflection of the new name across all platform interfaces including dashboards, reports, and account selection menus, streamlining account management and maintaining data continuity.
