fix(tui): broken tick chain after form/dialog + retries off-by-one

Update() routed form and confirm-delete states before handling
time.Time ticks, so those handlers swallowed the tick command and
permanently broke the refresh loop. After opening any form or
delete dialog, the TUI stopped auto-refreshing until restarted.

Move time.Time and WindowSizeMsg handling before state dispatch
so ticks always fire regardless of view state.

Also fix fmtRetries off-by-one: FailureCount=1 displayed as 0/N
instead of 1/N due to an erroneous subtract-one.
