Ambiguous court hearing start times passed

[solidgoldpig]

We allow the user to enter freeform text for start time of a court hearing

There is no indication of what's a valid time in the hint, but we do provide examples when a validation error occurs.

The example shown 12:00 has led some users to enter strings such as 2:00. While the input is valid, it results in the start time being recorded as 2am. This is probably not what the user intends.

We should should probably:

• stop accepting 24hr XX:XX as an allowable input format
• show something like this as an example for example: 10am or 2.30pm

Alternatively we could spot and query the user when an ambiguous[0] time is entered

[0] Currently we have the following behaviour

2pm -> 2pm
2:00 -> 2am
2 -> ?? -> Invalid
14:00 -> 2pm
14 -> 2pm

NB. a simple number is fine is greater than or equal to 10, but ambiguous if less than 10.
