Further speed improvements with LFD initial load

Ref. https://github.com/Fliplet/fliplet-studio/issues/5817

1. Many functions have been updated to avoid using _.get() with . delimiter (or avoid using _.get() entirely) as this has proven to be quite inefficient.
2. Assignment of edit and delete permissions are delayed until the entry is opened for the detail view.

Affected functionality

• Initial load without a limit on initial entries
• Initial load with a limit on initial entries
• Render time
• Opening an entry
• Opening the "Me" profile in the Directory layout
• Filtering, search and bookmark filter
• Social features (bookmark, like, comment)
• Correctly referencing user's information in while commenting
• Opening an entry on load (using the dynamicListOpenId parameter)
• Determining who has access to insert, edit and delete entries
