1.1.75

Fixed

• list_3mf_plates no longer leaves out a painted filament when a part's mesh is too large to read. A mesh over 64 MiB, or past 256 MiB read in total, used to be taken as unpainted, so a filament painted on it could go unlisted. Such a plate now lists every filament the project declares and says filaments_complete: false, so a client offers a spare row rather than miss one that prints. Every other plate says filaments_complete: true. A sliced plate is unaffected, even when it shares the unread mesh with an unsliced plate, because Studio's own plate_N.json names its filaments. Checked with unit tests for the one-file and the total limit.
