fix(lint): replace explicit-any types + unused-expressions ternaries

Five files, all stylistic:

- useFlowPilotSession.ts: typed the axios error shape with a narrow
  inline type instead of \`as any\`.
- FlowPilotSessionPage.tsx: same — typed location.state once, then
  destructured.
- ScriptBuilderTab.tsx: handleViewScript was a placeholder no-op;
  declared the args properly with \`void script; void filename\` so the
  signature matches ScriptBuilderChatProps without no-unused-vars
  firing.
- TicketsPage.tsx: replaced 8 ternaries-as-statements (\`x ? f() : g()\`)
  with proper if/else blocks. Same control flow, satisfies
  no-unused-expressions, and reads better in the URL-param update paths.
