Original PR description

Currently, when a user attempts to duplicate multiple maintenance requests simultaneously,
the system throws a ValueError (Expected singleton). This PR fixes that.

### How to reproduce the issue:

- Install `mrp_maintenance` module;
- Open maintenance request list view;
- Select multiple records and try to duplicate them using the Action button;
- It will throw a traceback stating a singleton error.

### Expected behavior after PR is merged:

Now multiple maintenance requests will be copied without raising any errors.

Original PR description

Before this commit, _get_transfer_move_lines_values computed the amount for the last destination line from the global transferred balance, instead of reusing the amount already removed from the source accounts. The two values are rounded independently and can differ by a cent whenever the removed amount comes from more than one rounded source, producing an unbalanced journal entry.

Removing that condition the last destination line always absorbs the remainder fixes it.

Steps to reproduce:
1. Transfer model with 2 source accounts and 1 destination line at 15%.
2. Post moves for the period: account A balance 395.88, account B balance 252.16 (total 648.04).
3. Run `action_perform_auto_transfer()`.

Before: source lines -59.38 (395.88*15%) and -37.82 (252.16*15%), destination line +97.21 (648.04*15% rounded) -> entry off by 0.01. After: destination line takes the exact remainder, 97.20 -> balanced.

Original PR description

Portal users can edit Knowledge articles but should not have access to the voice recording feature, which is reserved for internal users.

The readonly component is already used in read-only views, so reusing it in the editor for portal users is safe, it still renders the existing transcription content correctly without exposing any recording controls.

Portal users can still edit the text content inside the component thanks to the editable descendants concept, which allows the editor to manage specific editable areas even within a readonly component.
