Allow configuring can enter permission in the permission editor

[smadbe]

Overview

In the permission editor, it is currently not possible de configure can_enter_* permissions. Add this for explicit entry activities.

Acceptance criteria

(edited on 26/08/24, on 28/08 (perm on giver))

• [ ] If the item is an activity which requires explicit entry, allow the user to configure the can enter permissions
• [ ] Otherwise, hide completely "can enter" perm part
• [ ] The "Can enter" perm panel should be on top of other permission
• [ ] the panel should have a single switch "Whether the users with 'info' view permission are allowed to enter this activity. The activity must be also correctly configured to allow entering."
• [ ] The switch is disabled when "from" is isInfinite (see existing function)
• [ ] When the switch enabled, two fields are displayed: "from" and until
• [ ] The 2 fields are date+time fields without any date picker (but human readable)
• [ ] Some kind of format validation has to be done before saving
• [ ] By default, when enabling the switch when the previous value was infinite, set "from" to now and "until" to 2099-12-30T23:59:00Z (you should create a farFutureDate constant at project scope for that)
• [ ] When date fields are shown, you should have a note in small somewhere: "The time is entered in your own timezone (UTC+1)" where "UTC+1" is the browser current timezone.
• [ ] When the switch is disabled, both saved values are "9999-12-31T23:59:59Z" (which should be a backendInfiniteDate project constant)
• [ ] when the panel is collapsed, we should be able to see the summary. Something like: "no", "from ... until ..."
• [ ] IF the group/user has computed or current view permission >info & can enter from or until is defined: display in red on top of the can enter panel "As the group or user has currently "can view >= content" permission, the configured entering times have no effect, the group or user will be able to enter the activity at any time the activity allows it."
• [ ] the giver (the current user) must have "can_grant_view >= 'enter'" to change entering dates. Otherwise, it is just greyed out as it should be for the can_view modification section.
• [ ] Proper testing has to be done to check the updates work as expected

Context: By "default" (when we haven't just created a contest for instance), there are no access, we haven't given any perm.. so we do not want the user to "enter" at all. So both from and until are at "9999-12-31T23:59:59Z" Then 3 cases:

• we want to allow entering is a given time frame, so we'll set a value for "from" and "until"
• we just want to set a end limit... and so the "from" should be "now" if there were no value before
• we just want to set a min start time... and so the "until" should be "9999-12-31T23:59:59Z" as we do not want it to end

When there is any of these options set.. then we are a 4th option, which is re-disable all entering access... so we should be able to set back to "9999-12-31T23:59:59Z" both value

New proposal

There is a single switch for "entering".

• When disabled: "The group/user is not allowed to explicitly enter the content with 'info' permission."

• When the switch is switched "on": the "from" is set to now; and the "until" is set to the local 2099-12-31T23:59:00 (or absolute 2099-12-30T23:59:00Z if easier)

• There is no date picker widget. The date format is human-readable.

• Next to the date field, we add "The time is entered in your own timezone (GMT+1)" where GMT+1 is the local current timezone.

• When the switch is disabled, both value are put back to "9999-12-31T23:59:59Z"
