info about char limit for user reports, long user reports cannot be saved

[goapunk]

URL: https://meinberlin-dev.liqd.net/ideas/2021-00619/
user: any
expected behaviour: As a user, I can write a text that fits the text field. Either there is info about a char limit or the field has no char limit but I can save it. In this case the info would be preferable, because reports should not be too long.
behaviour: Users cannot save reports that are too long, but do not get a hint or an error message.

@CarolingerSeilchenspringer @TeaJayyy this issue exists in both a+ and mb (and all other a+ based projects). Therefore a possible fix will also affect all projects. Any preferences how to solve this? One option would be to add a char counter and limit the input field to 1024, so you can't enter any longer text (like in the screenshot below) but this should then be designed or double-checked by @mcastro-lqd

@goapunk @TeaJayyy for mB we want char limit display everywhere so I think we can fix this with the re-design. I will make a story as it is not a bug since it has been always like this.
