(FEAT): Added support for room multi-filtering

[Yalilix]

What

• Refactored Rooms filtering UI from a top filter row to a bottom-right floating action menu (FAB-style).
• Added persistent quick actions for all filter categories: date, duration, room type, campus, and capacity.
• Reintroduced Reset all filters in the floating menu.
• Refactored RoomsTabView and BuildingsTabView into smaller view sections/bindings to reduce SwiftUI type-check complexity.
• Removed legacy, now-unused filter bar components.
• Updated local lint workflow to exclude generated/dependency sources from SwiftLint scope.

Why

• Improve one-handed usability by moving filter controls to a thumb-reachable area.
• Restore native navigation-title behavior (large -> inline on scroll) by removing top-row layout interference.
• Address compile-time instability caused by overly complex SwiftUI view expressions.
• Reduce maintenance overhead by deleting obsolete filtering code paths.
• Eliminate noisy lint failures from third-party/generated files that are outside app ownership.

How

• Replaced top FilterBar integration in Rooms with an anchored floating menu near the tab bar.
• Wired floating actions to existing filter sheets/state and applied reset-all through existing view model APIs.
• Split monolithic SwiftUI modifier chains into explicit computed subviews and bindings.
• Performed dead-code cleanup of old filter-bar-era files after reference validation.
• Enforced swiftlint --force-exclude behavior with explicit exclusion rules for .build/checkout paths.

The padding on your sheet heading isn't consistent between all the filters.

Some things that stick out:

Campus: You have an option for Any Campus, isn't this the same as not applying the filter at all? same with capacity, room type, duration you have clear options.
Duration: On iphone 16e ios 18 sim, the text looks squashed and distorted on the picker
Capacity: I don't really like the option to add your own capacity kinda defeats the purpose of the radio buttons? I'd change it to a slider if you want them to be able to specify exactly the amount.

There's no padding involved when dealing with sheets, it's the sizing of the sheet that makes it look inconsistent. sure I can change the sizing of each sheet but I need to manually check each and then compare for all, not ideal workflow.

Duration: I'll remove the font modifier that i tried to enlarge the slider.
Capacity: I would have to disagree here. If UNSW decides to make a room smaller to fill equipments, then our old slider range isn't accurate, and we would have to adjust it. Also, it's not a user-friendly experience if the user wants to slide to a specific number, which sometimes it's not easy to slide to their target number.

Just had crunch time at work, will look at this tomorrow

1. Agreed with visual padding between the sheet top and the header titles. The sheet content may have inconsistent vertical padding, to check just add a red border on all the sheet content.
2. The clear options are alright, they are useful for when you add a filter but then want to remove it. We could communicate the intent better, e.g. using destructive button style.
3. Yep the picker looks distorted, this may be an issue with the picker requiring too much space. Maybe just abbreviate the options to 30m, 1h, etc.
4. I think the slider can be finicky particularly with a large range available

Will revamp this PR as we’ve managed to reverse engineer Freerooms’ backend endpoints, allowing us to migrate the filtering logic server-side and better align with the existing API structure.
