iOS Keychain PlatformException -25299 on API Key Save

[ramishroshan]

What happened?

Environment:
OS: iOS
Application: OpenStrap Edge
Provider URL: https://generativelanguage.googleapis.com/v1beta
Steps to Reproduce:

1. Navigate to Provider settings.
2. Input Base URL and API key.
3. Tap Save.
   Expected Behavior:
   The application saves the API key to the keychain. If a previous key exists, it overwrites or clears the existing entry before saving.
   Actual Behavior:
   The application fails to handle the existing keychain entry, blocking the save operation and returning the following exception in the UI:
   Could not save your key to the keychain: PlatformException(Unexpected security result code, Code: -25299, Message: The specified item already exists in the keychain., -25299, null)
   Technical Context:
   The error maps to iOS errSecDuplicateItem. The application's keychain write method lacks a preceding delete or update operation to clear orphaned or existing keys before attempting a new insertion.
