feat(pillarbox): add default options for pillarbox

[jboix]

Description

Closes #167 by enabling several options by default. These changes enhance the out-of-the-box experience for Pillarbox and improve default functionalities to facilitate a smoother integration process. The options that have been enabled are as follow:

Live UI

Enabled the Live UI by default, providing the following features:

• A progress bar for seeking within the live window.
• A clickable button to seek to the live edge, accompanied by a circle indicating if the playback is at the live edge.

By default, the threshold for displaying controls within the live window is set to 120 seconds, and live playback is considered within 15 seconds from the seekable end.

EME

Enabled the EME (Encrypted Media Extensions) plugin by default to support DRM integration and ensure compatibility with protected content.

Responsive Mode

Enabled responsive mode by default to accommodate a broader range of devices and screen sizes. See Video.js responsive option and Video.js breakpoints.

Inline Mode

Enabled inline mode by default, ensuring content is played within the element's playback area. This prevents, for example, the player from automatically switching to fullscreen on iOS devices.

Forced subtitles

Enabled the use of forced subtitles by default. Forced subtitles are pieces of information intended for display when no other text representation is selected. They are used to clarify dialogue, provide alternate languages, display texted graphics, or present location/person IDs that are not otherwise covered in the dubbed/localized audio.

Changes Made

• Set liveui, responsive, playsinline, plugins.eme and html5.vhs.useForcedSubtitles options to true by default.
• Set liveTracker.trackingThreshold to 120 seconds and liveTracker.liveTolerance to 15 seconds.
• Added test cases to verify default values for each option.
• Documented each option individually, referencing Video.js documentation when available.
• Removed these options from the Demo player as well as the standalone player page.
