Not a big issue.. I hope.
The bracket, as above, is used to lift the engine out. It's held onto the manifold by the same nuts that hold the manifold to the cylinder head, so if the bracket has dropped, it means that the nut is missing or the stud has fractured, so you could/would also have an exhaust leak as a result.
To fix it, you will need to fit a new nut.. or if the stud is rusted/knackered/missing then you will also need a new stud.
To replace the stud you will need to remove the exhaust manifold and (for space reasons) the airbox.
To remove the exhaust manifold you will need to remove the heat shield.
To remove the heat shield, you will need to remove the lambda sensor. You may find it easier to also loosen the radiator fan (2 self-tapping screws into plastic, so not too tricky). You can leave the fan attached to its wiring but the lambda needs to be disconnected. The connector is a strange one.. you have to lever up the yellow insert "bolt" section that locks the connector halves together.. then pull the two halves apart).
Once you have the fan out of the way and the lambda out, you can detach the heat shield. That's held on by 6 x 10mm bolts. Some of these will likely be rusted in place and shear off rather than come out, so give them a lot of Plusgas penetrating spray and fit new bolts when you reassemble it (M6 x 25mm). Any sheared/not replaced bolts will cause the heat shield to rattle, so either drill the broken ends out for new bolts, or use steel cable ties to hold the shield in place afterwards.
Once the shield is off, you can access the 13mm manifold nuts. There's 8 altogether I think. Some will come of okay, others will unscrew and take the stud with them.. but don't worry about that.. just put it back in the same place and it'll work.
The manifold has a bracket holding it to the clutch bell-housing. If you remove the bolt holding the manifold to the bracket (or the bolt holding the bracket to the bell-housing, if the other one is crusty) then the manifold can drop down (if the fan isn't in place) enough so that you don't need to disconnect it from the exhaust. That will give you enough room to get a stud extractor onto the offending (snapped off?) stud and remove it. There's probably 1cm of it still sticking out.. so use a proper stud extractor and a lot of Plusgas to get it to shift. I have a socket thing that has a lot of vertical rods inside it... they grip the stud and act on it like a very grippy pair of pliers.
A new stud, a new manifold gasket and re-fit is all you need... although I would change any stud that looks remotely manky and fit new flanged nuts, since they're cheaper than the grief you'll save yourself next time you want/need to dismantle the manifold.
I think any competent garage should be able to do this job in an hour and a half or two hours tops.. If the heatshield bolts don't all shear off and need resolving, the biggest grief is actually disconnecting the lambda sensor connector without breaking it..
