In the UI there are many help tooltips shown via question mark icons that provide guidance for configuration forms.
Currently, these tooltips are formatted inconsistently across different sections of the interface, which affects readability and overall UI consistency.

It would be good to unify the formatting of all such tooltips (punctuation, separators, empty content).

Actual: Tooltip texts are formatted inconsistently depending on the section. Found inconsistencies:

• Geographical maps → Tile URL →List items are separated by semicolons.
• Users → Authentication → Password must contain → Avoid easy-to-guess passwords:  list items are not separated by semicolons.
• Administration → Audit log → Log system actions: missing a period at the end of the sentence.
• Monitoring → Problems → Update problem form → Convert to cause: missing a period at the end of the sentence.
• Users → Users → New user form → Password: list items are not separated by semicolons.
• Item Mass Update form → Preprocessing: tooltip contains an empty line.
• Top items widget → Advanced configuration → Item ordering section → Limit: missing a period at the end of the sentence.
• etc.

Expected: All help tooltips under question mark icons should follow a unified style:

• Consistent use of punctuation (periods at the end of sentences)
• Consistent separators for lists (e.g. semicolons)
