fix: 修复配额说明重复和undefined问题

- 在editStorageForm中初始化oss_storage_quota_value和oss_quota_unit
- 删除重复的旧配额说明块，保留新的当前配额设置显示

+
+This package provides a presigner based on signature V4 that will attempt to
+generate signed url for S3.
+
+### Get Presigned URL with Client and Command
+
+You can generated presigned url from S3 client and command. Here's the example:
+
+```javascript
+import { getSignedUrl } from "@aws-sdk/s3-request-presigner";
+import { S3Client, GetObjectCommand } from "@aws-sdk/client-s3";
+const client = new S3Client(clientParams);
+const command = new GetObjectCommand(getObjectParams);
+const url = await getSignedUrl(client, command, { expiresIn: 3600 });
+```
+
+You can get signed URL for other S3 operations too, like `PutObjectCommand`.
+`expiresIn` config from the examples above is optional. If not set, it's default
+at `900`.
+
+If you already have a request, you can pre-sign the request following the
+section bellow.
+
+### Get Presigned URL from an Existing Request
+
+```javascript
+import { S3RequestPresigner } from "@aws-sdk/s3-request-presigner";
+import { Sha256 } from "@aws-crypto/sha256-browser";
+import { Hash } from "@aws-sdk/hash-node";
+const signer = new S3RequestPresigner({
+  region: regionProvider,
+  credentials: credentialsProvider,
+  sha256: Hash.bind(null, "sha256"), // In Node.js
+  //sha256: Sha256 // In browsers
+});
+const presigned = await signer.presign(request);
+```
+
+To avoid redundant construction parameters when instantiating the s3 presigner,
+you can simply spread the configuration of an existing s3 client and supply it to
+the presigner's constructor.
+
+```javascript
+//s3 is instantiated from S3Client from @aws-sdk/client-s3-* packages
+const signer = new S3RequestPresigner({
+  ...s3.config,
+});
+```
+
+### Get Presigned URL with headers that cannot be signed
+
+By using the `getSignedUrl` with a `S3Client` you are able to sign your
+headers, improving the security of presigned url. Importantly, if you want to
+sign any `x-amz-*` headers (like the ChecksumSHA256 header in this example),
+you need to provide those headers to the set of `unhoistableHeaders` in the
+`getSignedUrl` params which will force those headers to be present in the
+upload request.
+
+```javascript
+import { PutObjectCommand, S3Client } from "@aws-sdk/client-s3";
+import { getSignedUrl } from "@aws-sdk/s3-request-presigner";
+
+const s3Client = new S3Client({ region: "us-east-1" });
+const command = new PutObjectCommand({
+  Bucket: bucket,
+  Key: key,
+  ChecksumSHA256: sha,
+});
+
+const presigned = getSignedUrl(s3Client, command, {
+  expiresIn: expiration,
+  // Set of all x-amz-* headers you wish to have signed
+  unhoistableHeaders: new Set(["x-amz-checksum-sha256"]),
+});
+```
+
+### Get Presigned URL with headers that should be signed
+
+For headers that are not `x-amz-*` you are able to add them to the set of
+`signableHeaders` to be enforced in the presigned urls request.
+
+```javascript
+import { PutObjectCommand, S3Client } from "@aws-sdk/client-s3";
+import { getSignedUrl } from "@aws-sdk/s3-request-presigner";
+
+const s3Client = new S3Client({ region: "us-east-1" });
+const command = new PutObjectCommand({
+  Bucket: bucket,
+  Key: key,
+  ContentType: contentType,
+});
+
+const presigned = getSignedUrl(s3Client, command, {
+  signableHeaders: new Set(["content-type"]),
+  expiresIn: expiration,
+});
+```
+
+### PutObject with use of `hoistableHeaders`
+
+`hoistableHeaders` overrides the default behavior of not hoisting
+any headers that begin with `x-amz-*`.
+
+```js
+// example: Server Side Encryption headers
+import { getSignedUrl } from "@aws-sdk/s3-request-presigner";
+import { S3Client, PutObjectCommand } from "@aws-sdk/client-s3";
+
+const params = {
+  Key: "...",
+  Bucket: "...",
+  ServerSideEncryption: "aws:kms",
+  SSEKMSKeyId: "arn:aws:kms:us-west-2:0000:key/abcd-1234-abcd",
+};
+const s3Client = new S3Client();
+const command = new PutObjectCommand(params);
+
+const preSignedUrl = await getSignedUrl(s3Client, command, {
+  hoistableHeaders: new Set(["x-amz-server-side-encryption", "x-amz-server-side-encryption-aws-kms-key-id"]),
+});
+```
