Does RPI's IMAP server support server-side (SIEVE) filters?

Yes, but you need to create the filters using a client that includes a SIEVE filter editor. At this time, we know of Mulbery and later versions of Kmail. Mulbery is available in Linux, WIndows and MacOS versions, so there is a SIEVE filter editor available for the three most common platforms.

Note: You do not have to use the same client for reading email as you use for editing SIEVE filters. Once a filter is installed on the server it continues to operate, even when disconnected, regardless of the client used to read IMAP email.
