Subject: [PATCH] chore: mark fill_tris_low unpaired sites with FIXME

dimension.rs (x2), multileader.rs (x3), table.rs (x1) emit fill_tris
without a corresponding fill_tris_low. These will trip the debug_assert_eq!
added in the preceding commit when the entity appears inside a block
definition. Each site is marked with a FIXME referencing block_cache.rs:1397
and the correct fix pattern (split_ds on each vertex).
