Fixes & Improvements

Immersive Portals Compatibility

 - Fixed portal spawning one block too high
  Removed a duplicate + 0.5 Y-offset that caused IP portals to spawn half a block above their intended position,
resulting in portals clipping into the frame.

 - Fixed ghost portal spawning above the main portal
  The misaligned portal position confused Immersive Portals' cluster creation logic, spawning a second "ghost"
portal entity above the intended location. Correct positioning prevents this.

 - IP portals now require valid binding to spawn
  An Immersive Portal will only be created when:
   1. The portal is linked to another portal
   2. At least one portal in the link holds an Advanced TP Link in its inventory

 - No more quantum portal blocks when IP compat is enabled
  When Immersive Portals compatibility is turned on, quantum portal blocks will never spawn. If IP portal
requirements aren't met (not linked or missing TP Link), the portal interior remains visually empty instead of
falling back to quantum blocks.

 - Fixed coordinate teleportation when IP compat is on
  Unlinked portals using a TP Link item for custom coordinates would display destination particles but fail to
teleport. Replaced the unreliable execute in targetDim run tp command with programmatic entity.teleportTo() API
calls (the same approach the IP integration uses internally), with command fallback if the target dimension can't
be resolved.

Portal-to-Portal Binding

 - Linked portals now require Advanced TP Link
  Portal-to-portal teleportation now requires an Advanced TP Link item in at least one linked portal's inventory.
This is consistent with the IP portal spawning requirement and prevents unlinked portals from teleporting without
proper authorization.

Teleportation Reliability

 - Cross-dimension teleportation uses direct API
  All teleportation (both IP and vanilla) now uses entity.teleportTo() directly instead of relying solely on
command-based execute in targetDim run tp, which silently failed for cross-dimension teleports. Command fallback
is used only when the target dimension key can't be resolved.
