[frontend] remove valid_until column in indicators list (#8520)

[labo-flg]

Proposed changes

we chose to remove the column valid_until from the indocator list view as it's already too crowded.

Note that I added valid_until field specs to DataTableUtils (same format as indicator creation date, date+time) if we change our mind.

• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality
