Bedrock 1.21+ rejects minecraft:icon as a *block* component (it's an
*item* component), failing block registration with "child 'minecraft:icon'
not valid here". The post_office and mailbox blocks never registered, so
their recipes failed (silverlabs:post_office / silverlabs:mailbox missing)
and the items didn't appear in the in-game inventory despite the addon
being marked active in the world settings.
Reverts the additions made in f126eeb to those two block JSONs only;
the rest of the multi-mailbox script logic from that commit is unchanged.
Inventory icons now fall back to the material_instances texture (same
visual as before f126eeb).

Players can now place up to 5 mailboxes, each labelled like a lodestone
waypoint. Sending mail picks recipient then mailbox; redirect collapses
one of your own mailboxes into another and removes the source.
- v1 -> v2 schema migration runs once on boot; existing claims default to
label "Mailbox".
- Two-step send picker (skipped when recipient has only one mailbox).
- Post office root menu adds Redirect option.
- Per-entry break handling so removing one mailbox keeps the others claimed.
- minecraft:icon component + 16x16 inventory icons for both blocks.
- Refreshed pack_icon.
