Drop unused spatie/calendar-links dependency

[edalzell]

Closes#188.

@steveparks is correct — spatie/calendar-links is no longer used anywhere in this addon. All calendar/ICS generation goes through spatie/icalendar-generator.

Verification

A search across the whole repo (src/, tests/, resources/, routes/, docs, templates) for CalendarLinks / calendar-links returns exactly one hit: the require entry in composer.json itself. The only Spatie imports remaining are:

src/Http/Controllers/IcsController.php:12 Spatie\IcalendarGenerator\Components\Calendar
src/Http/Controllers/IcsController.php:13 Spatie\IcalendarGenerator\Components\Event
src/Types/RecurringEvent.php:9-11 Spatie\IcalendarGenerator\{Components\Event, Enums\RecurrenceFrequency, ValueObjects\RRule}
src/Types/MultiDayEvent.php:11 Spatie\IcalendarGenerator\Components\Event
src/Types/Event.php:12 Spatie\IcalendarGenerator\Components\Event
src/Day.php:6 Spatie\IcalendarGenerator\Components\Event

Change

Removes the "spatie/calendar-links": "^1.0" line from composer.json. Nothing else needed — no imports, no config, no docs referenced it.

This is purely a dependency cleanup with no behaviour change, but it does unconstrain consumers' dependency graphs (the ^1.0 pin was holding back anyone who wanted a newer calendar-links for their own use).

Note: the branch name doesn't match the pr-labeler.yml patterns, so you may want to add the chore label manually for release-drafter.

Note

Low Risk
Dependency-only cleanup with no runtime or API changes.

Overview
Removes unused spatie/calendar-links from composer.json. ICS generation already uses spatie/icalendar-generator only; no code, config, or docs referenced the dropped package.
