refactor(episode): define reusable episode atoms to prepare for up-next

[vladjerca]

This pull request, a symphony of deconstruction and reconstruction, refines the episode components within the client project, enhancing their modularity and maintainability. Witness the elegant transformation of code into a harmonious ensemble.

Component Refactoring:

• The monolithic Episode component, once a sprawling mansion of code, has been carefully dismantled and reborn as a collection of smaller, more manageable dwellings. Its styles, once entangled in a web of dependencies, have been liberated and refined.
• The EpisodeCard.svelte component emerges, providing a sturdy foundation for the episode's presentation.
• The EpisodeCover.svelte component, adorned with tags and imagery, captures the essence of the episode's visual identity.
• The EpisodeFooter.svelte component, a repository of essential details, completes the episode's presentation with concise clarity.

Tag Components:

• The EpisodeFinaleTag.svelte component, a herald of endings, marks the culmination of a narrative arc.
• The EpisodePremiereTag.svelte component, a beacon of beginnings, announces the dawn of a new chapter.
• The EpisodeTimeTag.svelte component, a chronometer of the ephemeral, captures the fleeting nature of time within the episode's context.
• The EpisodeTagContent.svelte component, a versatile vessel, provides a common structure for the diverse array of tags.

Upcoming Episodes:

• The UpcomingEpisode.svelte component, a harbinger of anticipation, presents episodes yet to unfold, utilizing the newly forged card, cover, and tag components.
• The UpcomingSchedule.svelte component, a chronicle of future events, has been updated to embrace the UpcomingEpisode component, discarding the remnants of the bygone Episode component.

Style Updates:

• The app.css grimoire has been inscribed with a temporary .ellipsis incantation, a spell to tame unruly text and maintain visual harmony.

Minor Adjustments:

• The AuthGuard.svelte component, a vigilant guardian, has undergone a simplification of its AuthGuardProps type definition, streamlining its form and function.

This meticulous refactoring, a testament to the pursuit of elegance and efficiency, paves the way for a more maintainable and adaptable codebase. The episode components, now liberated from their monolithic constraints, stand ready to face the future with renewed vigor and versatility.
