fix(mleader): new multileader inherits the current MLeader style (#94)

A new multileader was built from defaults and ignored the current
MLeaderStyle, so the style editor's settings had no effect on it (the
renderer reads the entity's own fields, not the style). commit_entity_handle
now copies the style's content/path type, text attachment/alignment/angle,
colours, sizes, scale and landing into the new entity (enum types
round-trip through i16 since the entity and style enums are distinct).

Text styles already render correctly and tables already resolve their
style live via table_style_handle, so no change was needed there.
