[LIMS-1905] Display grid box and location in cassette position selector

[gfrn]

JIRA ticket: LIMS-1905

Summary:

Grid box and position should be displayed when assigning a sample to a gridbox position, instead of buffer/concentration/grid characteristics. When scientists are loading grids into cassettes, they don't care about sample characteristics, but rather, the position of the grid they just "pulled" from the grid box.

Changes:

• Display grid box and location in cassette position selector

To test:

• Go to https://local-oidc-test.diamond.ac.uk:9000/proposals/bi23047/sessions/100/shipments/118/gridBox/new/edit, give the grid box a name, click any of the available slots and add a sample
• Check if sample details were displayed (concentration, buffer...) in the selector pop-up:

• Go to https://local-oidc-test.diamond.ac.uk:9000/proposals/bi23047/sessions/100/shipments/118, click any of the cassette slots
• Check if the grid box you just added shows up alongside its sample in the selector

• Create a sample with a very long name, check if ellipsis are displayed in the cassette when that sample is assigned to a cassette position
