fix: handle Notion API's nested response format change

[amaran-th]

Description

Fixes an issue where the main page shows "Nothing!" with 0 tags due to a change in the Notion API response format.

Problem

The Notion API response structure for block and collection has changed:

• Before: block[id].value → block data directly ({ type, properties, created_time, ... })
• After: block[id].value → { value: { type, properties, created_time, ... }, role: ... }

This causes rawMetadata.type in getPosts() to be undefined, failing the type check and returning an empty array [].

Solution

Uses ?.value ?? fallback pattern to support both the old and new response formats.

• src/apis/notion-client/getPosts.ts: Unwrap nested collection and block values
• src/libs/utils/notion/getPageProperties.ts: Unwrap nested block value

Please check src/libs/utils/notion/customMapImageUrl.ts too. I had trouble fetching thumbnail images that were uploaded directly to Notion.

I fixed like this:

Thank you for the comments!
This PR already addresses that. In getPageProperties.ts, the block data passed to customMapImageUrl is now properly unwrapped:

const blockEntry = block?.[id]?.value as any
const blockValue = blockEntry?.value ?? blockEntry // ← unwrapped block data
// ...
case "file": {
  const Block = blockValue // ← passes unwrapped data with correct `id` and `parent_table`
  const newurl = customMapImageUrl(url, Block)
}

Could you check if thumbnail images work correctly with this fix applied? If the issue persists, it may be a separate problem worth investigating.
