[PB-1379] Feat:password protected sharing

[apsantiso]

Users need to share their public links with a password to protect their data. To accomplish this with zero knowledge, the next changes are proposed.

• Add encryptedPassword field to the sharingModel.
• encryptedPassword needs to be encrypted with the public code (which we don't store).
• Allow frontend to create a public sharing with password in one step (just enable encryptedPassword in the DTO)
• Enable one endpoint to edit/create password for an already created public sharing.
• Enable one endpoint to remove password protection from a public sharing.
• Enable one endpoint to return public shared item info. We need to show users basic information of the item they are going to access to. (we just return size, plainName and type).

Please change the labels of the tests to accommodate 'When, then' pattern. Apart from that is all OK.
