[COLLAB-CON-6] (feat): editor can add their tiles

[kevinkim-ogp]

TL;DR

• Allow editors to add their own tiles
• Update cleanup

What changed?

• Editors can now add their own tiles to flows, with the flow owner automatically granted owner permissions on those tiles
• Dynamic Data Filtering: Updated getDynamicData to show editors both shared tiles and their own tiles, while viewers only see shared tiles in the current flow
• Connection Management: Removed owner-only restriction for adding tile connections while maintaining it for other connection types
• Delete Tile from flow_connections when the Tile is deleted
• Delete all connections in flow_connections when the Pipe is deleted

How to test?

Adding Tiles as an Editor

• Verify that Editor can view their own Tiles in the selector
• Verify that all Pipe collaborators are added to the Tiles with the correct roles
  • Viewers added as viewers
  • Editors added as editors
  • Owner added as editor
• Verify that Owner can still add their own Tiles and the Pipe collaborators are added correctly
• Verify that Viewer still cannot add Tile

Deleting Pipe

• Verify that connections in flow_connections are also deleted

Deleting Tile

• Verify that Tile connections in flow_connections are also deleted
