Fixes #23234: Hash API tokens

[amousset]

https://issues.rudder.io/issues/23234

See https://www.notion.so/rudderio/Hash-des-tokens-d-API-ddb9ec15820e4a81875b2a235d3f32e5 for details.

Technically, in the webapp:

• Nothing changes in the LDAP schema, we only change the content of the token field
• Centralize token management (hash, generation) in ApiToken. This will ease future modifications and ensure consistency.
• Changes in the API:
  • On get request, return an empty token field if it is hashed.
  • On put/post that modify the token, return the clear-text password in the token field to pass it to the user

The frontend changes are straightforward:

• New window based on modals, allowing to copy the clear-text token, opened after account creation or regeneration of a token.
• Changes in the token column:
  • Don't display it if there are not v1 tokens (and use the earned space for displaying creation date)
  • Move the regeneration button to the actions column
