Replace continuous surplus distribution with two fixed layouts per table.
Breakpoint at 120 columns — matches how btop/k9s do it.
Compact (<120): short headers (LAT, UP%, RT, ST, MON, SENT, VER),
tight fixed widths, no surplus guessing.
Wide (≥120): full headers (LATENCY, UPTIME, RETRIES, STATUS, MONITORS,
LAST SENT, VERSION), generous widths.
Sites tab keeps content-aware NAME sizing + sparkline flex.
All other tabs (Alerts, Maint, Nodes, Users) use simple fixed tiers.
Removed old computeTableLayout/colDef/tierCol/pickTier — no longer needed.
