fix(studio): clarify S3 access key dialogs (#51070)

## Problem

The S3 access key creation dialogs are wider than their contents, use
plural titles for one key pair, and call the name field “Description”
even though the table calls it “Name”. The save state also implies both
values disappear, although only the secret does.

## Solution

Use the small dialog size for both states. Use singular titles, label
the field “Name”, shorten the create button to “Create”, and clarify
when the secret must be copied. The API field remains `description`.

## Review instructions

1. Open a project’s **Storage > S3** page and select **New access key**.
Check the dialog width, title, Name field, and Create button.
2. Create a key and check the save dialog width, singular title, and
secret visibility guidance.

## Summary by CodeRabbit

* **Updates**
* The credential form now labels the field “Name” and uses “Create” for
the submit button.
* Confirmation text now clarifies that the access key is bucket-wide,
bypasses RLS, and its secret is shown only once. It also refers to a
single access key instead of using S3-specific wording.
