[TECHNICAL] OCS sharing and space members refactor

[joragua]

With the new implementation for OCIS shares listing (#4876), it's necessary to refactor all classes and methods related to the legacy sharing implementation to keep the codebase consistent.

OCS implementation → Use the Ocs prefix.
Graph API implementation → Use the Graph prefix (already done) ✅

Moreover, an additional check is needed in the XML files used for space members and shares to ensure that the ids are generic and consistent.

TODOs

• Refactor OCS classes adding the Ocs prefix
• Refactor XML files used for space members and shares
• Move the adapter and the recycler view setup for roles in AddMemberFragment to onViewCreated method
• Add a delay to the members search to avoid repetitive requests when user types quickly
• Use extension functions to bind roles, date picker and other UI elements
• Refactor the members filter to match the implementation in AddGraphShareFragment
