Issue Description

Guinea-Bissau's locale file has inconsistent translator comment AND translation order compared to the established convention.

Current (inconsistent):

#. %s (estimated, observed).
msgstr "%s (estimated, observed)"

Should be (consistent with 50+ other countries):

#. %s (observed, estimated).
msgstr "%s (observed, estimated)"

Background

During review of Sudan's locale file, we discovered that the established convention across the holidays library is to use "observed, estimated" order in both translator comments and translations. Guinea-Bissau is currently the only exception to this pattern, with both its comment and translation using the wrong order.

Solution

Update BOTH the translator comment and translation in GW.po to use "observed, estimated" order to maintain consistency with the rest of the codebase.

Required changes:

1. Fix translator comment order
2. Fix translation order
