Removes voided/flagged entry flags

Updates journal entry flags to align with Beancount's limited flag support.
Beancount only uses cleared (*) and pending (!) flags.

Removes the VOID and FLAGGED flags and recommends using tags instead
(e.g., "! + #voided" for voided entries, "! + #review" for flagged entries).

Updates the API to reflect this change, removing the ability to directly
"reject" an expense entry via the void flag.  Instead, instructs users to
add the #voided tag in Fava.

Updates reconciliation summary to count entries with voided/review tags
instead of voided/flagged flags.
