//As an organizer or participant, I want to be able to apply search (by name) on list of participants, so I can easily find specific participants in the list.
//
**Acceptance Criteria: **
* An organizer or participant (or any user who comes upon the the EventDetails page) should be able to apply "Search for participants" functionality on participant list within registration details (organizer and participant view) as shown in wireframe
* Before a search is applied, the instructional text ("Search for participants") should be displayed in light grey
* The search should function by the user typing a username and the results automatically being placed.
* Note that we have discussed that the search box component exists in [[ https://www.mediawiki.org/wiki/OOUI | OOUI ]], but we need to build the search logic.
* Out of scope:
** Infinite scrolling of participant list (this will be handled separately in T308576)
** No-JS experience with a button for search (this will be handled separately in T310152 and it is lower priority; it can be in V0 or V1)
