[Draw area] Enforce manual override option on “Draw area” tasks

[gino-m]

Adapting details from #3148 to "Draw area":

This introduces a new option set by the organizer called "allow manual override" on "Walk/draw area tasks":

Details:

• The location lock will be on by default when the task is first opened.
• If true, the user can pan the map to disengage location location (current behavior of "Draw area").
• If false, the location lock will be disabled, and the cannot pan/zoom the map (current behavior of "Capture location").
• The tooltip will be the same as it currently is for "Draw area", but when location lock is on will also show info shown in "Capture location" task.
