🐛 fix(EditChannelModal): hide empty “API Config” card for VolcEngine Ark/Doubao (type 45)

The VolcEngine Ark/Doubao channel now has a hard-coded base URL inside the backend, so it no longer requires any API-address settings on the front-end side.
Previously, the input field was hidden but the surrounding “API Config” card still rendered, leaving a blank, confusing section.

Changes made
• Added `showApiConfigCard` flag (true when `inputs.type !== 45`) right after the state declarations.
• Wrapped the entire “API Config” card in a conditional render driven by this flag.
• Removed the duplicate declaration of `showApiConfigCard` further down in the component to avoid shadowing and improve readability.

Scope verification
• Checked all other channel types: every remaining type either displays a dedicated API-related input/banner (3, 8, 22, 36, 37, 40, …) or falls back to the generic “custom API address” field.
• Therefore, only type 45 requires the card to be fully hidden.

Result
The “Edit Channel” modal now shows no empty card for the VolcEngine Ark/Doubao channel, leading to a cleaner and more intuitive UI while preserving behaviour for all other channels.
