fix(validation): allow hashtag in git branch names

Branch names containing '#' (e.g. feat#123) were rejected by
VALID_BRANCH_REGEX when saving a git provider configuration, even
though '#' is a legal git ref character.

Add '#' to the allowed character set. The change propagates to the
backend zod schemas and all provider UI forms, since they share this
constant.

'#' is not a shell injection vector: the regex still rejects every
character needed to terminate a command (; | & $ ( ) ` newline space
quotes), and '#' only starts a shell comment at the beginning of a
word, never mid-argument as in 'git clone --branch feat#123'.

Fixes #4585
