fix(activities): i18n keys + retry useOwnedTickets after transient failure

i18n: add the missing keys the ticket purchase + owned-tickets
surfaces use across en/es/fr — activities.detail.{buyTicket,
buyAnotherTicket, viewMyTickets, ticketsOwned, unlimitedTickets}
and activities.filters.myTickets. Without these the runtime fell
back to the literal key strings + spammed [intlify] warnings; the
filter chip rendered the bare key text on logged-in sessions.

ticketsOwned uses i18n pluralization so "You have 1 ticket" vs
"You have 5 tickets" both come out correct.

useOwnedTickets: the hasAutoLoaded guard prevented retries after
a transient backend failure (e.g. an LNbits restart mid-fetch).
The composable would stay stuck with tickets = [] forever, so the
buyer landing on a fresh detail page right after a transient error
saw no badges anywhere. Detect the "previous load didn't actually
hydrate" state (lastLoadedUserId still null while authenticated)
and retry on the next useOwnedTickets() call.
