improve study loading pages

10317 is super slow, current guess is due to amount of data ... a comparison between studies:

[I 240122 08:26:33 web:2161] 200 GET /study/description/10317 (127.0.0.1) 43387.91ms
[I 240122 08:26:44 web:2161] 200 GET /study/description/data_type_menu/?study_id=10317 (127.0.0.1) 10286.08ms
[I 240122 08:26:46 web:2161] 200 GET /study/description/baseinfo/?study_id=10317 (127.0.0.1) 12210.12ms

[I 240122 08:26:02 web:2161] 200 GET /study/description/data_type_menu/?study_id=550 (127.0.0.1) 641.92ms

Ideally every page should be in less than a second.

FWIW those times are as admins (load everything) as a regular user (only public), which are better but still over 1s:

[I 240122 08:32:14 web:2161] 200 GET /study/description/10317 (127.0.0.1) 13384.37ms
[I 240122 08:32:19 web:2161] 200 GET /study/description/data_type_menu/?study_id=10317 (127.0.0.1) 4982.58ms
[I 240122 08:32:21 web:2161] 200 GET /study/description/baseinfo/?study_id=10317 (127.0.0.1) 6925.24ms

Fixed with #3350.
