One date picker across the whole product, and folders you can rename and safely delete

Two things that were never anyone's headline feature and were quietly costing everyone time. Every date field in Solstral now uses the same calendar. Until today they were the browser's built-in date boxes, which meant the CRM looked like a different application depending on which browser you opened it in, ignored your theme entirely, and in some of them offered no calendar at all - just three grey boxes you tabbed between. There is now one picker: a proper month grid in your workspace's colours, with today marked, Today and Tomorrow shortcuts, a clock column for the fields that need a time, and past or future dates greyed out where a date genuinely can't be chosen - a booking window's end date won't offer a day before its start. You can still just type. The field takes today, tomorrow, +7, +2w, 25/12 or a full date, and reads it when you leave the field - if it can't read what you typed it leaves your existing date alone rather than guessing. Dates are read the way they're written here: 3/4 is 3 April. One deliberate exception: public forms on your own website keep the native control, because on a visitor's phone the operating system's own date wheel is better than anything we can draw, and those pages carry your styling rather than ours. And folders can now be renamed and deleted everywhere they exist - flow folders, website folders, the Content Library, email templates, and the label groups in your shared inbox. Some of those could already do both, some could only delete, and the flow folders couldn't be renamed at all: a typo in a folder name was permanent. Every rail now has the same pencil and cross on hover. Deleting a folder tells you what's in it first. If it holds anything, the confirmation names the count - “Onboarding holds 3 flows” - and states plainly that deleting the folder keeps every one of them and moves them to Unfiled. That was always true; it just wasn't said, and “Delete folder?” reads like it will take the contents with it. Nothing inside a folder has ever been deleted along with it, and nothing is now. Renaming also catches a name you already have in that spot before it fails, rather than after.
