Build 1.15.1848

Performance and reliability improvements:

• Improved service reliability in case of a DNS change.
• Improved performance of the data prefetching.
• Improved consistency guarantees in the local cache when errors occur.
• Added CLI option to activate single snapshot. See `lucid help activate` and `lucid help link` for more.
• Added more verifications during filespace initialization to ensure that the provided objectstore credentials have all necessary access rights.
  
  Bug fixes:
• Fixed data cache issues when viewing snapshots.
• Fixed some links in LucidApp that lead to the website.
• Fixed a rare crash on unlink that degrades user experience.
• Fixed a bug that does not allow to create a snapshot without a name.
• Renamed all "file space" strings to "filespace". Might affect any automation that depends on parsing Lucid CLI output.
• [macOS] Fixed of a mounting failure on fresh macOS installation (before system reboot).
