User may have created multiple allocation supplies for the same release/type/node

It prevent to change suspended Support Request to open again.

`Path` objects are immediately converted to a string.
This can only be done easily in tests for now, as slapos.core has to
still support Python 2 users in other parts of the code, and `os.fspath`
was added in Python 3.6.

See merge request nexedi/slapos.core!686

  If failover textarea is rendered, we ensure that at least the software type is set, in case it exists.

   This prevents bad software.cfg.json break the form while editing some instance.

  In case maileva is used, accountant needs access to system event module for add
  maileva exchanges. This role should be removed once Maileva integration be refactored

without the option --ignore-installed (even with
PIP_BREAK_SYSTEM_PACKAGES=1), pip3 upgrade on Ubuntu 24.04 would report:

   This is for backward compatibility.

  Clean up and update script to reflect the current usage
   Use Object rather newTempBase, so listbox columns are simpler to read

  Rename Base_getEventList to WebSection_getEventList since we only expect Web Section as context
  No need specific script to get Titcket Url (merged into WebSection_getEventList)
  No need Folder_getOpenTicketList features, since the will be a single use case for all tickets
  Update tests to follow up the changes.

   We want to unify the feeds, so per compute node/instance tree feeds should are gone.

    User should use the panel websection instead, so drop all
    code to request the rss feed for renderjs runner ui.

    Users should rely on Panel only for rss feeds.

   - Drop others rss feeds that are not **slapos_master_panel/feed
   - Keep backward compatibility with **slapos_master_panel/feed/critical, responding same as /feed
   - Keep backward compatibility with **slapos_master_panel/feed/invoice, responding same as legacy messages
   - Drop all feeds that were used over renderjs_runner

- accountants can see Subscription Request to pay deposit
- provide permission to create automated payment transaction

  The hardcoded trade condition dont exist anymore, so create one
  to ensure it is reseted.

   ledger cannot be changed otherwise the lines aren't grouped automatically like before.

   Otherwise, whenever you run the tests multiple times, it ends up failing by selecting the wrong one on the listbox.

   Be consistent and also search for a Remote Node, since it can also contain Compute Partitions.

  The trade condition is only mandatory for automated invoices, if the accountant does things manually, it is
  not required to create/use one.

   We do expect that all trade conditions be attached to a business process, so for manual accounting
   the condition changed.

    Se would like to skip consistency check if the invoice isn't automated (ledger) and has no lines,
   otherwise this consistency check should still apply as usual.
