Review and update Spaces IA for cross-platform consistency

[kittykat]

We want to use the same strings and have same (within the confines of prioritising platform-specific behaviours) IA for Spaces on all platforms, but especially so for iOS and Android. The work for this issue should be based off IA figma.

Things to look for:

• Interactions
• Strings

For this task to be complete, we needs to:

Discovery tasks

• As a team, review current designs

Design tasks

• Review IA flow on how user receives invites to a space and a room #178
• Converge on suggested room preview in Spaces #181
• Converge on Explore rooms view #184
• Converge on Spaces menu in left panel #205
• Converge on left panel string to add a Space #206

Development tasks

• Do not repeat suggested rooms which have been joined in the list of "Suggested rooms" in the Rooms tab element-ios#5747
• Update landing location after user joins a Space element-android#5334
• Fix highlighting showing which Space is selected element-android#5346
• Space preview: long press on joined rooms and suggested rooms behaves differently and the string below is not helpful for both #185
• Update suggested room preview to behave the same way in all cases element-ios#5771
• Remove Spaces feedback from left panel element-android#5486
• Update left panel string to "Create space" element-android#5516
• Add "Invite people"to the space menu in the left panel and update menu order element-ios#5810
• Update Spaces menu ordering and capitalisation element-android#5524
• Converge on Explore rooms view for Spaces element-android#5658
• Bring leaving space experience in line with Web element-ios#4850
• Bring leaving space experience in line with iOS element-android#5728

Descoped

• Reach parity on actions from the invite sheet #179
• Compile screenshots of areas where the room/space preview sheet is used for Android and iOS #177
