[electrophysiology_browser] Replace Physiological Annotations with Events

[jeffersoncasimir]

This PR aims to improve the current compliance to the BIDS standard. Loris-MRI counterpart: #1041
Partially addresses #8910.

This replaces references to annotation files with references to event files.

This PR deletes *_annotation_* tables. The corresponding required event tables already exist.

+minor improvements to the EventManager and AnnotationForm components.

This PR brings in the following limitations:

• Events can no longer be created via the interface (support coming soon)
• Events can be modified, but the currently supported fields are by default read-only or disabled (Name and time)
• HED tag support is extremely limited (better support in imminent PR: [electrophysiology_browser] HED Tag Support #9033)

TODO: Raisinbread modifications

TODO: Get official server-side solution + Add to documentation.

• Determine required request time limit
• Determine required memory allocation limit
• Determine procedure for increasing when needed

Both of the above needed to be increased for certain requests.

@regisoc can you review this?

Nice work!

• global logic looks good. Some questions for the back-end class.
• Still some TODOs in the code. I avoided repeating all comments. The comment on the first one should be valid for all similar following it.
• rename permission electrophysiology_browser_edit_annotations to electrophysiology_browser_edit_events?
• Some cleaning to do (commented lines to remove/keep)?
• Not tested yet. I might need help setting up testing env.

I will put that here so we do not forget them. Note after tests:

• Event download button disabled or not working.
• Error epoch.properties is undefined following that process:
  • open event panel
  • edit one event
  • submit this event
  • close the event submit with the top-right "x".

@jeffersoncasimir let me know if you need another round of test this morning.

New pass:

• error on epoch resolved.
• new errors due to multiple config db calls that can vary from config.xml. Unify calls for config check to $config->getSetting("dataDirBasepath"); in electrophysiologyevents.class.inc (one in _updateArchives one in update).
• Archive events file tgz created and downloadable, but archive is corrupted. Not corrupted, but not a gzip archive? Using tar xf <file> works, but not when using tar xzf <file>?
