-- Two related, small changes:
--
-- 1. profiles.is_agent: distinguishes the 5 real CS agents (Mayvel, Mon,
--    Jurina, Kate, Rubyrose) from the 7 management/reviewer accounts
--    (Edwin, Quinty, Dominic, Andrew, Kenn, Bjorn, Berry), matching
--    legacy's own DEFAULT_AGENTS list, which never included any
--    management/reviewer names. Defaults false so nobody is silently
--    marked an agent by omission; the 5 real agents are explicitly
--    flipped true below by their confirmed agent_id slugs (0022).
--
--    This is a DIFFERENT axis from is_active (0029) — is_active is
--    "on/off the roster right now" (any team member, agent or not);
--    is_agent is "is this person one of the 5 CS agents at all," which
--    never changes day to day. /api/agent-roster (feeding /schedule)
--    should only ever show real agents, so it now filters on both.
--
-- 2. invoice_profiles.full_name: seeds Edwin's row with "Edwin" (first
--    name only, no last name confirmed yet). Everyone else's full_name
--    is left '' (the column's existing default, 0012), which the UI
--    already renders as a fallback to agent_id/"—" — so this is purely
--    additive, nothing else changes behavior for the other 11 until
--    their real names are confirmed and added the same way.
