feat(inbound-filters): Add an issue action that drafts a custom filter from the event

[shellmayr]

• Adds "Add Inbound Filter" to the More Actions menu on issue details.
• Opens the custom filter modal with one condition per property the shown event has: exception type, exception message, country, release, IP address. The user removes the rows they do not want.
• Escapes event text as a Relay glob and folds line breaks into *. Raw exception type and message win over symbolicated ones.
• Moves the modal, the condition specs, and the save mutation from the settings table into customFilterModal.tsx. The modal now owns POST and PUT and invalidates the list query.
• Shown only with inbound-filters-v2, inbound-filters-v2-ui, and inbound-filters-in-product-flows. Disabled without project write access.
• Tracks the click as add_inbound_filter on the issue action analytics event.
• Lands after feat(inbound-filters): Register the inbound-filters-in-product-flows flag #126851 registers the flag. Rollout for the test orgs is getsentry/sentry-options-automatorref(app-platform): Move feature flagging into decorators #10091.
