[full-ci] Optimize share loading part II

[JammingBen]

Description

Continuation of #7580

• Remove loadCurrentFileOutgoingShares and loadIncomingShares mutations. Instead, incoming and outgoing shares are now being loaded via loadSharesTree(). This avoids getShare() requests from being executed multiple times.
• Decouple shares member loading from shares loading in store. This reduces the fetching of space members to a minimum and improves the structure of the code.
• Fix reactive loading of share indicators in sidebar details panel.
• Fix reactive loading of space member count in the spaces overview.
• Fix loading of indirect shares within spaces.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

This is ugly... We can't take the storageId of the current resource for each of its parents. This currently results in incorrect indirect shares being displayed when both of the following applies:

a) You are in in nested folder (at least 2 levels deep)
b) You (re-)load the page within the folder. Navigating from the outside into the folder should be fine.

Nice job! 💪 Only some nitpicks about mutation naming, see comments.
