[BUG] The page/list command only shows you pages you have sent

[chiizujin]

Describe the bug

The page[/list] command only show pages you have sent (or sent to yourself), not those you have received.

Pages on Jazri account:

15:06:24 to Chiizujin:> test
15:11:38 to Chiizujin:> another test
15:23:17 to Jazri:> self test
15:23:17 from Jazri:< self test

The Msg is being created with only the sender (and Admin) having read permissions, not all of the receivers:

locks=(
    f"read:id({caller.id}) or perm(Admin);"
    f"delete:id({caller.id}) or perm(Admin);"
    f"edit:id({caller.id}) or perm(Admin)"
),

Which means that they get filtered out here in the page command:
pages_we_got = [msg for msg in pages_we_got if msg.access(caller, "read", default=True)]

I'm fine with fixing this but I just want to make sure this isn't the intended behaviour first, though I suspect this isn't intended because of:

rstrings.append(
    f"{received[-1]} is offline. They will see your message "
    "if they list their pages later."
)

Expected behavior

I expect (possibly mistakenly) that page should show pages I have received as well as those I have sent.

The page system had previously completely ignored the locks system, so I think this is most likely just an oversight when fixing that.
