feat(admin): Mod panel tweaks + improved title ID input control

[ashquarky]

Resolves #XXX

Changes:

Future Changes are going to require all communities to have accurate TitleIDs set, so here's some changes for that and general mod panel tweaks.

• Change Icon and MiiIcon to the new component style, with folder structure and a type parameter for variants. Inline SVG icons are now called "UIIcon" to avoid the name clash.
• Add extra details to report rendering as requested by mods (PID view, link to reporter page, timestamp details)
• Bundle admin.js with main js so it's one large script. Only affects admin view.
• Port mod panel client code to TypeScript and refactor all event handlers into the new style with data- attributes.
• Make search bars into a component and use normal HTML forms instead of JS.
• Improve TitleID control so it can accept decimal, hex and dashed format TitleIDs. Hex and dashed IDs are commonly found on community wikis. IDs will always be displayed in dashed format.

Dashed, hex and decimal formats:

All displayed as hex after saving:

• I have read and agreed to the Code of Conduct.
• I have read and complied with the contributing guidelines.
• What I'm implementing was an approved issue.
• I have tested all of my changes.
