feat(web): better tooltips and uniformity (#474)

* - fix: changed all {text,bg}-{teal,indigo}-* color properties to {text,bg}-{blue}-* so there is only one dominant primary color in the UI -- blue
- enhancement: added `cursor: pointer` to the PageButton component (used in pagination)
- enhancement: modified TitleCell to use the new Tooltip component and modified the width selectors to a more sane default value, now instead of scrolling one just has to tap the cell to see it's untruncated value
- enhancement: modified the Tooltip component to use react-popper-tooltip (which in turn uses popper.js) which is a much better alternative, since it uses auto-positioning in case there's not enough space and some things aren't as broken as in the previous version (e.g. there was a problem with forcing the previous tooltip to use a specific width)
- enhancement: added a useMedia hook selector from the react-use repository, which might come in handy in the future for better/easier decoupling of Desktop and Mobile UI/UX patterns via JS (versus CSS-only)
- enhancement: made the mobile navbar more visible and clear. also fixed previous path === "/" bug which was fixed on desktop.
- fix: fixed table headers/footers so they're rounded
- enhancement: made pagination components more compact (buttons and show N result selector)

* changed {ring, border}-indigo-* to ring-blue-*

* build: add yarn.lock

* fix: formatting warnings
