feature request: Support for ordered and unordered bullets

Feature Description

currently none of the client (web/app/desktop) has support for bullets like other apps do
suggestion is to add option for numbered bullets and unordered bullets too
where user can select an option and the automatic continuation on next line

Motivation and Use Case

when someone has to send the message in key points they have to manually enter - <message> on each line
no automatic continuation
this feature will

• help improve user experience
• reduce manual work
• more universal format for message composer

Implementation Ideas

for UX

1. integrated buttons in the formatting toolbox
2. shortcuts like - and 1. and a space for auto-convert into list
3. auto increment bullet number of add new bullet on new line
4. using keyboard shortcuts

Additional Context

for implementing this:
phase 1 :
improvement of existing bullet support or migrating to new logic

phase 2: // currently implemented in draft PR
auto increment support

phase 3:
more bullet options like a. A. * added

phase 4:
adding dedicated buttons in formatting toolbar

Start by tracing the existing bullet support in the message composer and reviewing the formatting toolbox entry point mentioned in the issue. Compare the proposed shortcut, continuation, numbering, and toolbar phases with the draft implementation; done should be defined for the selected phase and verified across the listed client targets.
